Delivery contents Skin Response![]() Delivery contents eSense Skin Response– Mindfield® eSense Skin Response Sensor Delivery Contents eSense Skin Response Bundle– Mindfield® eSense Skin Response Sensor NotesIf you would like to have a longer cable between the eSense and your smartphone or tablet, you can extend the original cable of the eSense. More about this in our article. Some newer iOS devices without the classic 3.5mm headphone jack need an adapter. More about this in our article. 3. Technical DataMeasurement using direct voltage with a voltage source of 0.61V DC and a source resistance of 61.5 kOhm. The maximum DC patient auxiliary current according to EN-60601 medical device standard is thus within the limit value of 10uA DC. Sampling frequency: 5 Hz (5 measured values per second). The measured values are saved for exporting the data and can be exported as a CVS file in the app. Resolution of the measured values: 18 bit, rounded to 2 decimal places, i.e. 0.01uS in data export without rounding. Measuring range: 10 kilo-ohms to 1 mega-ohm corresponding to 100uS .. 1uS. Possible deviation of + – 5% over the entire measuring range on average. 4. Combination possibilities eSense sensors & Combined FeedbackThe eSense sensors can be combined with each other with restrictions. You can use this combination in our eSense app in both an Open Training and a Procedure. Since the eSense Skin Response, eSense Temperature and eSense Respiration each require the 3.5mm headphone jack in your smartphone or tablet, these 3 sensors cannot be combined with each other. The video explains the exact procedure for combining the eSense. The settings in the eSense app are shown and how a later evaluation of the combined measurements can be made. eSense PulseSince the eSense Pulse connects via Bluetooth®, you can combine the eSense Pulse with each of the other sensors (via the 3.5mm headphone jack). This results in the following possible combinations regarding sensors and biofeedback parameters (in brackets):
*The eSense Respiration can only be used in combination with the eSense Skin Response, as it is based on the Skin Response. ![]() ![]() ![]() 5. Analysis of eSense data (CSV)You can export the data from the eSense app and then further evaluate it with other programs (such as Microsoft Excel™ or Google Spreadsheets™). In this guide we will show you all the steps, from exporting from the eSense app to importing and evaluating in Microsoft Excel™ and Google Sheets™. For the eSense Pulse we also have a complementary article about the Kubios HRV software. The examples shown in this guide are mostly related to the eSense Skin Response. In principle, however, data from the eSense Temperature, eSense Pulse, eSense Respiration or eSense Muscle can be processed in the same way. Exporting measured values from the Mindfield eSense app![]() The app also includes an archive where you can save and export your recordings. Export data By tapping on the export icon in the upper right or by tapping the “Export as CSV File” button at the bottom you can export the recordings in .csv format with all common apps (e.g. send via Messenger™, WhatsApp™, email etc.) or simply on your phone or in your cloud (e.g. Google Drive™ or Dropbox™). ![]() The data is exported as.csv file (comma-separated values). You can open this file format e.g. with Microsoft Excel™ or Open Office Calc™ (free alternative to Excel). If you like working with Google, Google Sheets™ (Google Tabellen™ in German) can also be an alternative to Excel for you. You can also open and visualize your exported.csv files and easily access them from multiple devices via the cloud. Google Sheets has similar functions as Excel and a very similar operation. General NoteThe exported files are always CSV files. CSV stands for “Comma separated values”. This means that a comma separates the values in the file (,). These CSV files can be opened and edited with programs such as Microsoft Excel™, Google Sheets™. It is also possible to import and edit with frequently used programming languages or frameworks such as R™, Python™, Numpy™ or Tensorflow™. These instructions refer to Microsoft Excel™ and Google Sheets™. We recommend beginners to use Google Sheets™ rather than Microsoft Excel™, because it is easier to use and it often works better with our measurements (f.i. the seconds are not automatically prefixed to dates, see in the section on Excel). Google Sheets is also a bit better at quickly creating charts automatically. Using Excel makes more sense if you are already more familiar with Excel. You can find Google Sheets™ here: https://www.google.com/sheets/about/ Your settings at Excel™ and Google Sheets™ are decisive. The eSense app adapts the measured values to the language used. In English, the numbers are usually separated by a dot. Therefore, 1.5 in the English version becomes 1,5 in the German version. So if you open the CSV file with Excel™ or Google Sheets™ and the numbers don’t make sense, it’s usually because of different languages in the eSense app and Excel™ or Sheets™. In principle, therefore, the following applies: If you use Excel™ or Sheets™ in German, you should also use the eSense app in German. If you use Excel™ or Sheets™ in English, you should also use the eSense app in English. This saves you the first two steps (replacing decimal separators and splitting values into columns) and you can start directly with step 3 (Apply skin conductance against time). Microsoft Excel™1. Replace decimal separator (only necessary if you have different language settings in Excel™ and the eSense app)
![]() 2. Split values into columns (only necessary if you have different language settings in Excel™ and the eSense app) The values for time and measured value are still in the first column, separated by commas or semicolons. You must divide them into two columns.
![]() 3. Format seconds correctly (optional) Excel often formats the seconds in the first column automatically to a date. Unfortunately there is no way to disable this, it is preset by Excel. But there are a few ways to solve this: https://support.microsoft.com/en-us/office/stop-automatically-changing-numbers-to-dates-452bd2db-cc96-47d1-81e4-72cec11c4ed8 4. Draw skin conductance against time

![]() 6. Draw skin conductance against SCR
![]() ![]() Google Drive (Google Sheets™, recommended)As in Excel™, complications with the separators can also occur here. The exported files are always CSV files. CSV stands for “Comma separated values. This means that a comma separates the values in the file (,) Google often tries to format the data automatically. Then it can happen, among other things, that the measured values are interpreted as date. To prevent this, you should first make sure that you select “Format” -> “Number” -> “Number”. 1. Replace decimal separator (only necessary if you have different language settings in Google Sheets™ and the eSense app)
![]() 2. Split values into columns (only necessary if you have different language settings in Google Sheets™ and the eSense app) Depending on their language settings, the values for time and measured value are both in the first column, separated by commas or semicolons. You must divide them into two columns.
3. Apply skin conductance against time.
4. Enter main conductance against highlights
![]() The diagrams made via Google Sheets can also be embedded via iFrame. 6. Streaming eSense data to a PC/Mac/Browser (eSense Web App, OSC)We offer advanced users such as biofeedback trainers, therapists and coaches the ability to stream the measurement data of the eSense sensors via the eSense app to a PC as well. Thus, group courses can be realized or remote training, whereby the trainee can be in a very different place than the trainer. Even a remote supervision is easy. All features described below are not public but available on request. In our online shop, we offer an eSense set for professional users (https://mindfield-shop.com/produkt/esense-set-exkl-sdk) , where the use of these features is included in the price. After unlocking, you can see these features in the settings in the eSense app when you scroll all the way down. Currently, we offer you two ways to transfer data from the eSense App to the PC: our eSense Web App or the OSC Transfer. Both can even be used in parallel but usually it makes sense to use either one of them. The OSC protocol is used for fast and timely streaming and actually comes from the music industry. OSC is open-source and there are a lot of possibilities to integrate the protocol into existing software. eSense Web AppWith the eSense Web App for iOS and Android, we have also developed an eSense web app for the browser, which mirrors and supplements the eSense mobile app. You need an account for the eSense app and one of our plans. You can analyze your recorded data in the browser (with the basic plan) or even stream it in real time to a PC (with the premium plan). With the eSense Web App you can view the measurements of several and different eSenses simultaneously and in real time. For example as professional user you can watch and look after a group of 5 different users, each with their own eSense. Different sensors, for example an eSense Skin Response with an eSense Pulse or Temperature or Respiration, can be freely combined. The users can even be distributed around the world. They just need a smartphone, an eSense sensor, the mobile app and a booked plan. More information about the plans soon here. ![]() As a private user, you can also benefit from the fact that you can see the graph even better with a large screen and enlarge individual areas. You will find the eSense Web App at https://esense.live. There you can log in with the same account (username and password) as for the eSense mobile app. OSC Transfer![]() OSC (https://opensoundcontrol.stanford.edu) stands for “Open Sound Control” and is an open-source network protocol developed by the University of California at Berkeley. It is widely used in the music industry because it is great for processing different signals in real time (for example, at a concert where it is important to match multiple microphones and lights in real time). This makes this protocol particularly well suited for the data transmission of several eSenses in real time. Due to the wide distribution in the music industry, there are already some extensions and plugins which you can adjust relatively easily and use in a self-designed software. These are usually found in all common programming languages like for Android, iOS, Java, Javascript, C ++, Python and many more. To use OSC with the eSense app, you must define the IP address of the user receiving the data. This can be a local IP address or an IP address on the internet. You can define the ports as you wish. You should pay attention to firewalls, as they like to prevent the flow of data. You can also define a variable in the app to be able to assign different eSense. This will allow you to sort or filter the eSense (or users) and analyze it better. The OSC transfer is aimed at programmers of (Windows or Mac) software who want to integrate the data from the eSense. The available OSC libraries in the usual programming languages make such integration very easy. You can enable OSC Transfer in the general settings in the eSense app (see screenshot) 7. Duplicate eSense on a large screen (screen mirroring)With the eSense app, it is possible to display the screen content of a tablet or smartphone on a larger screen, which is known as stream mirroring. This allows you to watch your biofeedback training at home on your big screen TV, for example, which can improve your training. The following instructions can be used with all eSense devices. An adapter is always required: Smartphone / tablet (with the eSense app) We generally recommend iOS devices. AndroidWith Android, it only works with newer devices that have a USB-C output and a 3.5 mm jack plug. Android devices with micro USB do not work. Our recommendation is this adapter on Amazon: JSAUX USB C HDMI Adapter, 4K USB Type-C Thunderbolt 3 auf HDMI Adapter https://amzn.to/3Use9HpeSense Skin Response, Temperature and Respiration: If your device no longer has a 3.5mm jack plug and you are already using a USB-C to 3.5mm jack adapter for the eSense, unfortunately you cannot use the USB-C to HDMI adapter. Wireless with HDMI dongles (Miracast / Chromecast etc.)We have had rather mixed experiences with the common HDMI dongles. There are many options, but the dongles generally require an external power supply and are rather complicated to set up. We therefore advise against using them, but in principle it works and is an alternative if no further adapter is available in the device (because the device only has a USB-C but no longer has a 3.5mm jack plug). iOSYou can connect a Lightning Digital AV Adapter or a USB-C Digital AV Multiport Adapter to the Lightning port of your iOS device and use an HDMI cable (sold separately) to connect your iOS device to a TV or projector. In principle, this is possible with any iPhone, iPad and iPad Pro that are also compatible with our eSense app. We expressly recommend only original Apple adapters. Others may work under certain circumstances if they have MFI certification. However, Apple could change something at any time, so we do not recommend third-party adapters, which may not be updated quickly enough and may no longer be compatible. You can find the original Apple adapters on Amazon: Apple Lightning Digital AV Adapter https://amzn.to/3y7ndtY
Apple USB-C-Digital-AV-Multiport-Adapter https://amzn.to/3wdvoEx
eSense Skin Response, Temperature and Respiration: iOS also requires a USB-C to 3.5mm jack adapter for these eSense devices (this is not required for the eSense Pulse and Muscle as they connect to the smartphone or tablet via Bluetooth). This means that if you want to use an iPad with the eSense, it should also have a 3.5mm jack connection. The iPad Mini 5 would be an example, this is slightly older, but still has the 3.5mm jack connection. For normal iPads, the 9th generation devices were the last with the 3.5mm jack connection. We recommend https://www.refurbed.de/c/ipads/ or https://www.rebuy.de/kaufen/apple-tablets to purchase these at a reasonable price. Wireless with AirplayWe have had good experiences with AirPlay. The setup at Apple is very simple, the best solution is probably a used Apple TV from 50 euros: Apple TV 4K Gen 1 https://www.refurbed.de/p/apple-tv-4k-5th-gen/ Mini projectorThere are now also relatively good mini projectors available for an acceptable price. In our experience, these are not particularly bright, but in a sufficiently dark room they are an option. The projector only needs an HDMI input. 8.

General information about skin conductanceThe term “skin conductance” refers to measurable changes in bioelectrical properties of the skin. The skin conductance depends on the activity of the skin’s sweat glands and reacts to even the smallest changes, which are far from being perceived by us as wet hands. A very small, completely harmless and imperceptible electrical voltage is applied to the skin via the two electrodes of the eSense Skin Response, over which a very small current flows. The greater the activity of the sweat glands, the moister the skin and the better the current is conducted. The skin conductance increases as a result. The eSense Skin Response measures skin conductance in micro-Siemens (µS, µ means “millionths” and “Siemens” is the unit of conductivity). The term “skin resistance” is also commonly used to describe the same phenomenon and refers to the reciprocal of the skin conductance (1S = 1/Ω). The activity of the skin’s sweat glands is determined by the autonomic nervous system. Sympathetic and parasympathetic nervous systems are parts of the autonomic nervous system. The sweat glands of the skin are innervated exclusively sympathetically, i.e. without the influence of the parasympathetic nervous system, and are thus a good indicator of “inner tension”. When exposed to stressful stimuli, the sympathetic nervous system activates all the emergency functions of the organism and puts it in a heightened state of readiness to act: pulse and blood pressure rise, glucose levels in the blood increase to provide a readily available source of energy, and the level of attention becomes higher. Of central importance to the measurement process explained here is that the hands become moist. ![]() We also often know these situations from our own lives. For example, think of a speech you gave in front of a group or a job interview. If you were excited in these situations, you can certainly remember the cold, proverbial sweaty hands? One theory on the cause of this phenomenon is that our ancestors’ moist hands gave them a better grip when grasping in stressful situations, such as when fleeing through terrain. Once the threatening situation is over, the parasympathetic nervous system gains the upper hand: pulse and blood pressure slow down, and the glucose circulating in the blood decreases. The organism is switched to rest to ensure recovery. The hands become dry again. The increasing activity of sweat glands and consequently the increase of skin conductance is clearly visible under the influence of a stress stimulus. This stimulus can be mental activity, emotional arousal, deep breathing or even a startle, for example, by unexpected clapping of hands or loud dropping of an object on the floor. Try it out for yourself with the eSense right now! We combine the measurement and feedback of skin conductance in the eSense app with guided relaxation exercises, including guided meditations, and offer you an overall experience beyond biofeedback. In addition to extensive feedback options, you have the possibility to evaluate their measurements with many statistics, document your progress and export the records as CSV and PDF files. Your data belongs only to you! You have full access to the raw data. 11. Skin response and biofeedback trainingStress and its vegetative symptoms can be greatly reduced through biofeedback training, where you intentionally work on lowering your skin response. Skin response is a universal tool for biofeedback training. It is widely used in the therapy of anxiety, panic disorders and specific phobias. Further fields of use are high blood pressure, tinnitus and sleep disorders. If you suffer from a serious disorder or medical condition, always consult a professional physician or therapist, and do not attempt to treat yourself. The eSense Skin Response is not a medical device and may only be used for stress reduction training. The Skin Response is a precise device. It can measure the smallest changes which would be impossible to recognize yourself. Have a look at the following example of a measurement to see how insightful the results are ![]() because of stressors. The peaks are recognized and colored by the app. Measurements are done by placing two electrodes on two fingertips of the same hand. The dark-colored lower side of the electrode should be in good skin contact. Other positions for the electrodes and other electrode-types are possible as well. The goal of the feedback training is twofold: A reduction of the permanent, basic level of stress and a reduction of the immediate stress response to a particular stimulus. A biofeedback training consists of four training stages. Schedule for the first training about 60 to 90 minutes of free time in which you can conduct the training undisturbed and flexibly. It must also be differentiated between different types of stress. There is “bad stress,” distress, and there is “good stress,” eustress. You need to ask yourself if you are stressed because you feel overwhelmed and are angry about something or because you are upset. Or are you “stressed” because you are full of drive and are excited? In both cases, the eSense Skin Response shows elevated values. However, in the first case, this is to be judged negatively. In the second case, you can simply enjoy and use the active or euphoric state. 12. Skin Conductance Response (SCR)The Skin Conductance contains two components: the tonic, static „level“ and the phasic, fluctuating „reactions“, and these components are usually designated as Skin Conductance Responses (SCR). While the “level” is represented well in the average of the measured values, the eSense Skin Response also measures the amount of Skin Conductance Response (SCR) per minute. In general, a higher number of SCR per minute is an indicator for higher stress. Value from experience which is in alignment with scientific literature[1] suggests that a “relaxed” frame is between 0 and 5 SCR per minute. From 6-9 SCR/min starts an animated state. From 10 or even from 16 SCR/min, a level of stress or even high stress can be assumed. [1] Boucsein, W. B. (2011). Electrodermal Activity (2. Aufl.). Berlin, Deutschland: Springer. The SCR are great for comparing biofeedback-sessions to each other. If your goal for training is a reduction of stress, then the amount of SCR/min should decrease over several sessions. In the archive of the app, you can compare the different sessions to each other. The average value in µS of a session is an indicator for the “level,” hence how high your basis level of tension or relaxion is. You should also try to lower this while you are doing stress reduction training. The average value also takes the SCR into consideration and is falsified with many SCR/min. You should, therefore, use as quiet a frame as possible without any SCR to determine your own “stress level” in µS. We have colored the SCR/min in the eSense app. Low SCR are green or yellow and high SCR/min are orange or red. While making a measurement, the recognized SCR are colored within the curve. Two examples from our app: ![]() ![]() (yellow and orange) In the right diagram, there is also the time in which the values rise, fall or have been steady. With rising stress, the curve rises more often and longer than it keeps steady or falls. This is also an ideal parameter to analyze and to compare biofeedback sessions. The whole process of detecting and calculating the SCR is a cycle of four steps:
The 4 Steps in detail
The cycle starts in the first step, the listening state. This is the standard default state. 2. Determining signal raise There are two ways for detecting the start of an SCR start. The values could either raise slowly with a small step or very fast with a big amplitude. This creates the following to conditions:
If the signal will fall just even 0.1 micro siemens during a raise, the app will drop out of this second step and return to the first step (the listening state) again. Otherwise it will continue with the next two steps 3 and 4. 3. Gathering and calculating SCR (fluctuation) If one of the two conditions from the second step above are met, the app enters this third step, the fluctuation. The first signal of the fluctuation period is the base value of a fluctuation signal. During the whole fluctuation period, the app is detecting the amplitude which is constantly changing. Then the app starts to calculate the SCR events globally and within a one-minute time window. This results in the SCR/min value. 4. Initiate recovery phase The fluctuation is considered to enter the recovery phase (the end of fluctuation) when the signal falls for more than 50% of the greatest amplitude of the fluctuation period. This is also the step where the color in the graph is changed (based on the quantity of SCR events that were occurring). The colors for the SCR background are also calculated (by dividing time intervals into equal segments and getting the sum of the SCR events from each segment). 13. Preparation and start of the appCreate the conditions needed for a successful training:
You should avoid all conditions that can make you sweat out of purely physical reasons, like intense physical activity before training or intense sunlight and heat. This could falsify your measured values. To obtain comparable results, you should try to keep your initial and ambient conditions constant through the series of training sessions. In comparison with other biofeedback techniques, you will need fewer sessions for a reliable success. 6-10 sessions should be sufficient. To keep focused throughout the entire session, you should limit each session’s length to about 30 minutes. If you start feeling tired while training, you should shorten your sessions and practice more often instead. Fixation of the Velcro-electrodesWrap the two electrodes around the upper or middle phalanges of your index and middle finger of the same hand. The dark lower side of the electrodes shall be in good skin contact. Using the non-dominant hand is advisable (e.g. the left hand for right handed people) because the skin tends to be a little less callused there. Attach the cables and wrap the tape another time around their clips to ensure a firm contact. ![]() ![]() You should neither tape the electrodes too firmly where you would block blood circulation, nor too weakly so as to let them slip and move around. Put your hand down onto a comfortable support where it can rest. Another note: If your values are below 1µS, the electrical contact through the clip is bad, or your skin is dry and maybe callused. Check the contact clips, or change your hand or the position of the electrodes if necessary. If the conductance is permanently bad, we have listed several tips in the FAQ for the eSense Skin Response to improve the conductance. Usually gel electrodes are necessary. Don’t continue with the training if the values are below 1µS and solve the cause first. The next step is to start the app. At the beginning you can choose between a free training and a procedure. We recommend that you start with a procedure. We present you both below. ![]() ![]() Wählen zwischen Prozedur oder freien Trainings nach Start der App 14. ProceduresA procedure consists of several assembled modules. With this new feature, you can build the perfect individual relaxation guide, do a stress test, use it for pre-defined biofeedback training or use it for research. There are many possibilities. During a procedure, your skin response or temperature (depending on the eSense sensor you have) will be recorded, and after the recording is made, you can see your results for each module and in total. ![]() We suggest you test the demo-procedures which are included in the app. Those will give you a guided overview of the different modules and functions of the procedures. The included procedures are also protected by a password in order that those can’t be edited or deleted by accident. You can any time create a copy of those procedures without a password and change it as you wish. We also explain in detail how you can create and edit your own procedures in the chapter procedures settings. 15. Open TrainingAs a second option you can also conduct an open training. This is compared to the procedures a bit more complex. We therefore explain a typical open training session which consists of 4 training phases. Preparation and start
![]() ![]() First stage (observe and experiment; determine your initial status)
![]()
Second stage (targeted Biofeedback training with the skin response)
Third stage (deliberate provocation, relaxation and stress coping)
Fourth stage (transfer; relaxation without feedback)
16. Electrode typesThe eSense Skin Response has a standardized push-button electrode connection. Therefore, it can be used with a wide range of electrodes. ![]() In order to ensure the comparability of measurements, once a specific type of electrode has been selected Once an electrode type has been selected, it should be used throughout. Please also note that 2 Velcro electrodes (and two spare electrodes) are included in the Skin Response delivery and 2 + 4 Velcro electrodes, 50 gel electrodes and 2 finger clips are already included in the Skin Response Sparset with additional electrodes. More in the article on the delivery contents. Velcro electrodes![]() + Easy to use + Reusable + Cheap – Worse conductivity You can order Velcro electrodes here: https://mindfield-shop.com/en/product/eda-velcro-electrodes-for-measurement-of-skin-conductance-8-pieces Finger clips (without gel)![]() ![]() + Easy to use + Reusable + Comfortable – Worse conductivity You can order the Finger clips here: https://mindfield-shop.com/en/product/gsr-finger-clips-without-gel-2-pieces Gel electrodes (disposable)![]() ![]() + Easy to use + Best quality of signal – Useable just once Our prior recommendation You can order the gel electrodes here: https://mindfield-shop.com/en/product/emg-ecg-eda-single-use-electrodes-for-adults-with-comfortable-breathable-fabric-pre-geled-50-pieces 17. Possible electrode positionsGeneral information for the skin preparation (independent from the electrode type): Skin preparation or skin cleansing is usually not necessary and also not recommended. It is enough to wash the hands, although the soap dries the skin and lowers the measured values. The same applies to the skin cleansing with alcohol. Greasy skin or skin that has just come into contact with hand cream should be freed of oily residues by being washed with lukewarm water and alcohol (70%) if necessary. Velcro electrodes![]() Wrap the Velcro electrodes around the upper and middle phalanx of the index and middle finger. Make sure the silver electrodes touch the surface of your skin directly. Then connect the press button wires with the electrodes. You can wrap the Velcro around the press button ends once again to stabilize the wires, as shown in the right image. Gel electrodes![]() We recommend the single-use gel electrodes. There are three different possibilities of the areas of conduction, as shown in the images. All positions are equivalent. Simply connect the electrodes wire through the press button connectors with the electrodes. Finger clips (without gel)![]() These EDA finger clips are simply put on the fingertips of the index and middle finger. Then the press button wire of the eSense connects with the electrodes (here, the wire should run forward towards the notch inside the clips). 18. Extending the cord of the eSenseIf you wish to use a longer cord between the eSense and your smartphone or tablet, you can extend the original cord of the eSense with a common, 4-pin, 3.5mm jack headset extension cord. We have tested three cords that have worked well: 2m cord: https://amzn.to/2kil5bj All three suggested cords cost between £6-8 and are available from Amazon. Alternatively, you should be able to use other 4-pin cords as well. 19. Smart Bulbs (optional)![]() The eSense app can support biofeedback via smart bulbs. Smart bulbs can change their colors and brightness and can be controlled via Bluetooth®. In combination with the eSense app, smart bulbs indicate your level of stress or relaxation through their lights. Currently, the eSense app supports the Magic Blue and Phillips Hue smart bulbs. Both are smart bulbs which can be controlled via Bluetooth®. The color as well as the brightness can be adjusted. From within the eSense App, you can connect to the Magic Blue or the Phillips Hue and use it in your biofeedback session. Here you connect to the Hue Bridge from the eSense app and select the desired lamps. Magic BlueUnfortunately, the Magic Blue is no longer in production. We have extended the eSense app to enable the use of Philipps Hue smart bulbs, which can be controlled via Bluetooth. But you still can find more information about the Magic Blue in our article Philips HueYou should be able to find the Phillips Hue in every well-sorted electronic store. You can also order it online. A list of the on- and offline-merchants can be also found on the page of the Phillips Hue: https://www.philips-hue.com/en-us We suggest you use one of the starter kits from Phillips, with the eSense. This also contains a colored bulb (‘Color Ambience’): https://amzn.to/3uzSFx8. The use of Philips Hue is available as an in-app purchase in the eSense app. You can also find more information about the Philips Hue in our article. 20. Philips™ Hue™ FAQWhich products from Philips Hue can I use with the eSense app?In general, all Philips Hue products are compatible with our eSense App and therefore can be used together with the eSense. We tested the most common products:
For the best experience, we recommend the Philips Hue White and Color Ambience, because with the colors, the feedback can be enhanced more than with only white colors. Especially we recommend using the Philips Hue Go, as it is mobile with battery and a very nice, complete lamp. How do I connect to the Philips Hue within the eSense App?You have 2 options: You can connect the Hue in the eSense app via the bridge with Zigbee or directly via Bluetooth (which is mainly the case with the newer Hue lamps). To connect to the Philips Hue products, open the eSense app and follow these steps:
How do I connect the Philips Hue within the Hue App?
How many Philips Hue bulbs/products can I use with the eSense app?We have successfully tested up to 9 products/bulbs (mixture of different type of bulbs, Hue Go and LightStripe). However, from 3 products and more the reaction time of the products/bulbs slows down significantly (Philips enables a maximum transfer speed of 100ms per signal and per bulb). Especially if you use several bulbs, a short distance to the Philips Bridge, the bulbs and your smartphone or tablet becomes more relevant. See also the next question about this. How far can the Philips Hue, the Hue Bridge and the smartphone or tablet be away?Usually the range is between 30 and 100 meter, depending on the environment. The range is less with objects in between (for example a wall in between can decrease the range). Also, if the Hue Bridge and your modem should be in another floor level, it can influence the range. However, the transmission of the signal by Philips is good enough so that there weren’t any problems with our tests in normal households with the signal. Just from 4 (and more) bulbs at the same time a recognizable lag can occur, see also the question above about this. A warning will be displayed in the app if you want to use more than 3 lamps at the same time. Where can I buy the Philips Hue products?You should be able to find the Phillips Hue in every well-sorted electronic store. You can also order it online. A list of the on- and offline-merchants can be also found on the page of the Philips Hue: https://www.philips-hue.com/en-us We suggest one of the starter kits from Philips for the use with the eSense. This also contains a colored bulb (‘White and Color Ambience’): https://amzn.to/3uzSFx8 21. Magic Blue FAQI can no longer find the Magic Blue in the Mindfield Shop.Unfortunately, the Magic Blue is no longer in production. We have extended the eSense app to enable the use of Philipps Hue smart bulbs, which can be controlled via Bluetooth. How do I connect to the Magic Blue?You connect to the Magic Blue from inside the eSense app. To connect to the Magic Blue, open the eSense app and follow these steps:
After you have followed these steps, the app will remember the Magic Blue you have chosen (you usually don’t need to follow these steps again, unless you want to use another Magic Blue). You should not pair the Magic Blue by the device generic Bluetooth® settings. What can I do, if connecting to Bluetooth® fails or the Magic Blue is not found?Restart the Magic Blue (switch the switch of your lamp off and on again). Especially if the Magic Blue is already switched on more than 1 minute, the Magic Blue stops sending the Bluetooth® signal to connect. Restarting activates the signal again and the Magic Blue can be found. Why can’t I find the device when scanning for Bluetooth® devices?Check the light from the Magic Blue to make sure the Magic Blue is switched on. If there is metal around the Magic Blue (for example a lampshade around the Magic Blue), it could shield the Magic Blue and block the signal. Make also sure that the Magic Blue is not connected to another phone or tablet already since the Magic Blue can just be connected to one phone or tablet at a time (see also next question). How many Magic Blue bulbs can I control at the same time?You can control one Magic Blue at the same time. How far can the distance between Magic Blue and phone or tablet be?Usually the range is 18 to 30 meters without any objects in between. It will be less with objects between the Magic Blue and your phone or tablet (for example a wall between the Magic Blue and the smartphone or tablet can decrease the range). How can I reset the Magic Blue?Just follow this video to do so: 22. Functions of the Mindfield eSense App![]() The eSense comes with the eSense app which you can load for free in the Google Play Store (Android) or Apple App Store (iOS). It offers a wealth of features for effective biofeedback training in a modern design. Essential functions are: the display of measured values as a bar graph, an oscilloscope, feedback via video, music, sound, vibration, and smart bulbs (Magic Blue and Philips Hue). You receive a comprehensive evaluation after each measurement and can compare measurements with each other in the archive and export them as CSV files. The app is available in English, German, Spanish, French, Italian, Portuguese, Ukrainian, Russian, Turkish, Dutch, Japanese and Chinese. The language is chosen automatically according to the set language of the smartphone or tablet. Download Links iOS: https://itunes.apple.com/us/app/mindfield-esense/id1141032160?mt=8 Android: https://play.google.com/store/apps/details?id=com.mindfield.boisystem.esense 23. General notes
In following the app is described in full details. 24. General view & Open TrainingPortrait![]()

25. Breath Pacer (optional)If you have toggled this option on in the settings, you can have the Breath Pacer displayed. In the settings you can choose between line, sphere or animation. ![]() ![]() You can configure the breath pacer in the settings. There you can freely choose inhalation time, hold, exhalation and hold in 0.1s increments. 26. Biofeedback Snake![]() You can also display the Biofeedback snake as an additional option. At the top left are appearing symbols which vary in color depending on the current measured value. The symbols are either green (further positive direction), yellow (slight negative direction), orange (strong negative direction) or red (very strong negative direction). After 10 green symbols you will also be rewarded with a star and after 50 green symbols even with a shooting star. If the snake goes over the entire screen you will see the last 5 minutes. The SCR events (Skin Conductance Responses) also contribute to the calculation of the color of the hands. 27. Survey (optional)If you have toggled this option on in the settings, a survey will appear after each measurement. This enables you to archive reproducible measurements and to document changes in your measurements (for instance, if you change the electrodes type or if you start to use the eSense while you are lying down instead of sitting). ![]() What is your position? Electrode type How do you feel? Note (here “Test tone and tactile”) 28. Pie charts (after a measurement)After the measurement (and optional survey), in the landscape mode, a survey appears with two pie charts: one shows your SCR while your measurement and another shows the time proportions of rising, falling or steady values (see screenshot). Here you can also swipe the screen to the left or right to change between the pie chart and the graph of your measurement. ![]() 29. Procedure Overview![]() Edit or delete procedure To edit a procedure, simply swipe it to the left in the overview. You can then tap the blue pen-symbol to edit the module.

MeditationsYou can also choose one of our guided meditations as a procedure. The breathing meditation is already included in the eSense app. We will also offer more meditations shortly as new free cloud procedures for users with account. The meditations thus offer you an easy way to train your awareness and attention and, at the same time, receive biofeedback. 35. Own media (photos, videos and audios)You can use your own pictures in the picture module, your own videos in the video module or your own music or melodies in the audio module in the procedures. Android usually enables this without any further problems. As long as you allow the eSense app to access your files on your device, you can upload them to the eSense app. iOS is a bit more restrictive. As usual, you can use your pictures from your device in the iCloud for pictures and videos. For audio files you need iTunes (or an alternative such as “CopyTrans Manager”). This is where your music or melody must be. You can find your music in iTunes (or CopyTrans Manager) under the tab “My Sound” and insert it into your procedures. We have a detailed video at https://www.youtube.com/watch?v=A_CRbmBeBBc where we show all the steps. On iOS the power saving mode must also be deactivated, otherwise the videos in the procedures cannot be played. 36.

37. In App Purchases![]() In-App Purchases 38. Archive (overview)![]() The app also contains an archive, in which you can save your measurements and export them as well. You can watch those in detail again, compare them to each other and export them individual or all together (as ZIP file). Recordings If you click on the clipboard symbol at the top right, you can mark one, several or all measurements. You can then export, analyze or delete the exported measurement (s). ![]() On the filter symbol you can choose whether you want to sort the measurements by name, date, length in ascending or descending order. If you want to delete a single measurement from this list, you can also tap on the trash can symbol to the right of the measurement. Analyze Time, Average of Session µS, Minimum µS, Maximum µS, Difference Min/Max µS, Time Increase, Time Decrease, Total SCR, % of SCR of Session. With this, you can recognize trends over time and over several measurements (if, for example, your % of SCR of Session decreases by regular training, you can see this here immediately). 39. Archive (individual view)![]() ![]() Export data Thanks to our export functions at the bottom of a recording, you can export the recordings in PDF or .csv format with all common apps (e.g. send via Messenger, WhatsApp, e-mail, etc.) or simply save them on your phone or in your cloud. The data are exported as a.csv-file (comma separated values). This format can be opened with Microsoft Excel or Open Office Calc (for free). If you like to work with Google, Google Sheets can be an alternative to Excel for you. You can open your exported .csv-files, visualize and access them via the cloud easily from several devices. Google Sheets has almost the same functions and interface as Excel. Note: We have also summarized more detailed information on CSV export and processing your data in an extra article on streaming and analyzing eSense data. ![]() SRC Parts of increase/decrease/steady In the pie chart you can see the parts in which the measured values where increasing, decreasing or steady. Export as PDF File You can export the measurement also as PDF alternatively. Note: This takes a moment. ![]() In Excel™ or Google Sheets™ Notice: If you open the .csv-file with Excel™ (or Google Sheets™) and your values make no sense, then there is usually a different set language in the eSense App and Excel™ and Sheets™. Note: We have also summarized more detailed information on CSV export and processing your data in an extra article on streaming and analyzing eSense data. ![]() 40. Marker featureYou can also set markers while you make measurements. For example, if you have a regular biofeedback exercise which involves breathing calmly at a specific point, you can set a marker in that moment when you breathe calmly. Later in the exported data, you can see the moment where you had breathed calmly. The marker feature comes in handy when you are making longer measurements with several actions. The markers can be displayed well in Excel: ![]() 41. Virtual Reality (VR) (f.i. Meta Quest 3)All our eSense sensors and our eSense app also work with VR (virtual reality) glasses. The prerequisite for this is a USB-C adapter (our recommendation: https://amzn.to/40eCoLR), which we now recommend anyway and which you can also order directly from us in the store with an eSense. The eSense app can be used as normal, with all its functions. After the one-time setup with SideQuest, no further special adjustments need to be made. In particular, the graph of the measurement as well as the photos and videos of the biofeedback training can be viewed in impressive detail with the VR glasses. We have created a video that shows the best way to use it: 42. Compatible Android and iOS devicesGeneralNote for all eSense: If you don’t have a device yet and/or want to buy an extra device for the eSense, we recommend depending on your taste either

According to our research, these options offer enough power for the eSense app, will remain upgradeable to the upcoming Android and iOS versions for some time, and are still reasonably priced. The Android devices also still have a normal 3.5mm jack input and do not require an adapter for the eSense. Starting from the iPad 10th generation (2022), the iPad Pro 3rd generation (2018), the iPad Air 4th generation (2020), and the iPad mini 6th generation (2021), iPads no longer have a 3.5mm headphone jack. From these models onward, you will need an adapter for the eSense. More information can be found in the general notice below under iOS. iOS devices compatible with the eSense
General note: Alternatively, you can use any other adapter with a DAC chip. We recommend this adapter on Amazon: https://amzn.to/2SnAUA1. We tested 11 alternative Lightning adapters from third-party vendors – only two of them worked. Therefore, we recommend either the original Apple Lightning adapter (https://www.mediamarkt.de/de/product/_apple-mmx62zm-a-2179668.html) or this compatible Lightning-to-3.5mm adapter, which we have successfully used with the eSense and also offer in our shop: Compatible Apple Lightning to 3.5mm adapter https://mindfield-shop.com/en/product/compatible-apple-lightning-to-3-5mm-adapter.

Important note about Android devices for the eSense Pulse: Important note about Android devices for the eSense Respiration, Skin Response and Temperature: Alternatively, you can use any other adapter with a DAC chip. We recommend this adapter on Amazon: https://amzn.to/2SnAUA1. Below are some Android devices that we have tested with the eSense Pulse, Respiration, Skin Response and Temperature and which work fine (whitelist). (Please note that this is only a very small sample and that the vast majority of devices worldwide work with the Mindfield eSense).
The following Android devices are NOT compatible with eSense Respiration, Skin Response and Temperature (blacklist). This list is not necessarily exhaustive. If you are not sure if your device is compatible, check if the microphone input is present as described above!
It is possible that these devices will work after all if you use the devices’ USB-C port instead. You can use a USB-C to 3.5 mm jack adapter for this purpose: https://amzn.to/2SnAUA1. 43. Adapter for Android and Apple devicesSome newer Android and iOS (Apple) devices without the classic 3.5mm headphone jack and with the newer Lightning / USB-C connector also work perfectly with the eSense. Please follow this order when using the adapter:
If the adapter with eSense is only plugged in after the app is already running and in Free Training mode (even if no training has started yet), connection issues may occur. If the eSense is not recognized and the signal fluctuates erratically, please close the eSense app completely and restart it. This should resolve the issue. AppleYou either need an original Apple USB-C (https://amzn.to/41zD2Gd) or original Apple Lightning (https://www.mediamarkt.de/de/product/_apple-mmx62zm-a-2179668.html) to 3.5 mm connection adapter (not included in the scope of delivery of the eSense). ![]() has a 3.5mm headphone jack, e.g. the iPhone X.) Android & AppleAlternatively, you also can use any other adapter with a DAC chip. We recommend this adapter on Amazon: https://amzn.to/2SnAUA1 ![]() An adapter is also only needed, if at all, for the eSense Skin Response, eSense Temperature and eSense Respiration (as these eSenses have a 3.5mm headphone jack). An adapter is never needed for the eSense Pulse and eSense Muscle (as these connect to the device wirelessly via Bluetooth®). General note: Alternatively, you can use any other adapter with a DAC chip. We recommend this adapter on Amazon: https://amzn.to/2SnAUA1.

You can analyze your recorded data (with the basic plan) or even transfer your data to a PC in real time (live streaming with the premium plan). The main advantage of this is that you can see the graph even better with a large screen and enlarge individual areas and have more advanced analyze features. ![]() ![]() With the eSense Web App, you can also view measurements from several and different eSense simultaneously and in real time, which allows a professional trainer client to design the workflow. You can find the web app at https://esense.live. There you can login with the same account (username and password) as for the eSense app. For more information on the eSense Web App and its capabilities, see also our article on streaming eSense data. ![]() The eSense app works with all our eSense except the eSense EEGenius. 45. Supervisor GuideSubscribe to a planYou must have activated a plan. You can book this in our mobile app (on Android and iOS), under Profile -> Plans. For sharing your measurments with a supervisor as client, the Basic Plan is sufficient (because the measurements are already uploaded to the cloud, so your supervisor can access your uploaded measurements). We also have an overview of different trainer-client scenarios here: https://mindfield.de/esense-app-fur-den-professionellen-anwender/ For the live streaming and custom live view, the client needs to have the Premium plan activated. ![]() ![]() Client sideNext you need to login to our Web App at https://esense.live/ ![]() In order to share your measurements with a supervisor you need to have the Basic plan activated (as described in the first step above) ![]() In the web app, you must enter the ID of your supervisor (with whom you want to share your measurements). For data protection reasons, this is unfortunately only possible in this way. This means that your desired supervisor must provide you with the ID and you must enter it in the following place and thus allow the supervisor access: ![]() (For privacy reasons, supervisor mediators are now shown with their initials only. The e-mail is no longer displayed, only the ID). Trainer sideFirst you need to login to our Web App at https://esense.live/ ![]() You must be a registered Supervisor. You can buy the Supervisor Plan here: ![]() In order to work with your client(s), the client(s) needs to
If you want to use the live streaming together with clients, the clients also need a stable internet connection. You can add clients by selecting them from the drop-down list. As the clients have previously explicitly granted you access, you should see your clients in the drop-down list. ![]() ArchiveAs Supervisor you can see, analysis and compare saved measurements of your clients.

Type in the email address of the client whose measurements you want to load and click on the “Search for id/email” Button ![]() ![]() Activate streaming to esense.live in the eSense mobile appIf you are a supervisor, you can activate real-time data transmission to eSense Web App (esense.live) in the eSense app settings. ![]() ![]() Custom Live View (Live Streaming)For the custom live view and live streaming, you need to have the Premium Plan activated (as described in the first step above). Klick on “Charts” -> “Custom live view” in the menu. Select the client from the drop-down menu, select the Sensor at “Type” and click on “Add custom Chart”. ![]() You can do this with several different sensors from the same user as well as see the measurements from several users at the same time. You could for example stream the Skin Response and Pulse from one client when the client does a combined measurement with the Skin Response and Pulse. But you also could have 2 or more clients all using an eSense Pulse at the same time and stream them next to each other (f.i. in a group session that you do online with several clients in different places) 46. Account and CloudYou can register your own, free account for the eSense app and book plans. You can also benefit from free, regularly added procedures without booking a plan. Thus, we recommend using the app with an account. With the plans you can mainly use the cloud and its functions and get also access to the eSense web app at https://esense.live. With the Basic Plan, you can save your measurements locally and online in the cloud and thus access your measurements from all devices and from anywhere. You also get access to the eSense web app. The Premium Plan includes all functions of the Basis Plan. In addition to your measurements, you can also save your custom procedures online in the cloud and thus access your procedures from all devices. (Attention: Technical limitations from Apple unfortunately do not allow the upload (and thus the synchronization) of audio files. The synchronization of picture and video files is possible, however). You can buy the Premium Plan here: https://mindfield-shop.com/en/product/premium-plan-for-esense-app-for-all-esense-sensors-annually/ There is also the Supervisor Plan. As a professional or commercial biofeedback trainer, you can use it to create individual procedures for your clients and share them with them via the cloud. You can buy the Supervisor Plan here: https://mindfield-shop.com/en/product/esense-supervisor-account-monthly-subscription-for-esense-app-and-esense-live You can also share your measurements with other users. You also have the option of transferring your data to the eSense web app in real time. To do this, activate “Real-time data transfer to eSense Web App” at the bottom of the settings. ![]() ![]() These plans can be used, among other things, to design a trainer’s client’s workflow.

Account ComparisonNote: Scroll the table left or right on mobile devices
2) Sharing with other users or groups possible 3) Sharing with other users possible Example cases for the different accountsSUPERVISORThe professional or commercial biofeedback trainer has a SUPERVISOR account so that he can create individual procedures for his clients and share them with them via the cloud. They can also create different groups and add their clients to them individually. This allows them to monitor and analyze their clients’ measurements over a longer period of time. You can buy the Supervisor Plan here: https://mindfield-shop.com/en/product/esense-supervisor-account-monthly-subscription-for-esense-app-and-esense-live/ PREMIUM PLANThe client who wants to work with a (professional) trainer and have access to all functions has a PREMIUM PLAN. This allows the client to share their recordings (both free measurements and procedures) with the trainer and other users. They can also upload their own procedures to the cloud and have them analyzed or adapted by the SUPERVISOR (trainer). BASIS PLANThe client who wants to work with a (professional) trainer needs at least this account so that he can share his recordings with the trainer (SUPERVISOR). WITHOUT PLANAnyone who simply wants to get a taste of the app does not need to join a plan to test its functionality. Example cases for the synchronization of measurements between accounts with different plansWithout account, without plan (and offline)All measurements are saved locally on the device. There is no synchronization with the cloud as there is no associated account. Users can only access their measurements on the device on which they were carried out. You can find the measurements in the archive under the Recordings tab. With account, without planThe measurements are linked to the user’s account but are not synchronized with the cloud. All measurements that are linked to the user’s account are displayed in the archive. The measurements can only be accessed if the user is logged into the account on the device on which the measurements were taken. You can find the measurements in the archive under the Recordings tab. With account, with basic or premium planAll measurements are linked to the user’s account and are synchronized with the cloud. All synchronized measurements that are linked to the user’s account are displayed in the archive. To synchronize old measurements that were created on the device before a plan was purchased with the cloud, you can select the “Synchronize with the cloud” button in the “Local session, performed without account” tab in the archive. These measurements are then assigned to the other measurements and disappear from this tab. Activate streaming to esense.live in the eSense mobile appIf you are a supervisor, you can activate real-time data transmission to eSense Web App (esense.live) in the eSense app settings. ![]() ![]() 48. GroupsThe accounts enable you to create your own groups or to join other groups. This allows you to share your recordings with your friends. Or you can work with a trainer as a client since you can share your recordings with the trainer. ![]() Create a group Tap on the plus symbol to create a group. Edit a group Tap on the 3 dots next to the group name You can then (if authorized) view and remove the members of the group or add new members. 49. Privacy policyThe eSense App does not collect any personal data, such as name, gender, date of birth, etc.. Each recording of measurement data is done under a general prefix such as “measurement”, supplemented by with the eSense sensor used, the current date and time of the measurement. The recorded measurement data cannot therefore be assigned to any person. The prefix of a recording, e.g. “measurement”, can be changed by the user in the settings and used for the assignment to a person. Users can decide whether to change this prefix to their name, for example. Then each measurement and also each CSV file exported from it contains the name of the user in the file name.
