Quick Overview

Mobile Biofeedback with your smartphone or tablet.

The Mindfield eSense Skin Response is a convenient sensor for measurement of the skin conductance via the microphone jack of a smart phone or tablet (Android and Apple iOS).


Biofeedback with the eSense Skin Response!

The Mindfield eSense Skin Response is a small sensor to measure your skin conductance using the microphone input of your smartphone or tablet (Android or Apple iOS).


With the eSense you can...

  • ...do biofeedback training
  • ...measurize and reduce your stress level
  • ...create and use a guide for meditation

Which iOS Devices are Supported?

  • Apple® iPhone® from 4S
  • Apple® iPad® from 2nd Generation
  • Apple® iPod touch® from 5th Generation
  • Apple® iPhone 7 and iPhone 7 Plus (in combination with the included Lightning to 3.5 mm Headphone Jack Adapter)


Which Android Devices are Supported?

  • All Android smartphones and tablets from Android 4.0
    Your Android device requires a 3,5mm jack (headphone jack) for external microphones!
  • If you plan on purchasing a device for using the eSense, we suggest the Amazon Fire 7 as an affordable tablet.


Skin Conductance

Your skin conductance depends directly on your state of relaxation or stress, making it a commonly used and very precise stress indicator. With the eSense Skin Response, you can precisely identify your stress level and reduce it with biofeedback training.

The eSense provides you in various ways with exact feedback about your momentary stress level, e.g. with measurement curves, video display and audio feedback features.

For the audio biofeedback, the eSense now has a headphone jack, so you can additionaly listen to music or audio books while training your stress level down!


Previous eSense App (for older devices)

This app is free and included with every eSense, it provides all features as described on this page. We recommend this especially with older devices. With this you can already do biofeedback training.

Skin Conductance / Skin Response

Skin response, also known as galvanic skin response (GSR), electrodermal response (EDR) or skin conductance (SC) is a method for measuring the skin's electrical conductance, which varies with its moisture level. Conductance is measured in µSiemens (µS) and is the inverse of electrical resistance.

The eSense Skin Response measures skin conductance between two Velcro electrodes attached to the index- and middle fingers. Active measurement involves applying a very low, unnoticeable voltage to the fingers.


Significance of Skin Conductance and Biofeedback-Training

In a professional, therapeutic context, skin conductance training is the preferred biofeedback training method for anxiety, panic and learning relaxation.

The sweat glands are controlled by the vegetative (sympathetic) nervous system and react directly to the smallest emotional, physical or mental changes. A rise in skin conductance is clearly visible under the influence of stress. Stress factors may be, for example, mental activity, emotional arousal, deep inhalation or frightening.

Even the smallest changes are made visible with the aid of the app, and can be used for biofeedback training to reduce stress.

detailed introduction is included in the free app.


Included with eSense Skin Response

  • Mindfield® eSense Skin Response Sensor

  • 2 velcro electrodes

  • Free app from Mindfield via the App Store or Google Play

  • Extensive instructions for effective biofeedback training.

Quick Guide to Usage

  • When you buy the eSense skin response you can download our free app from the App Store (Apple®) or Google Play (Android).
    (You can also download it in advance, but the app can not be effectively used without the sensor)
  • Fix the two velcro electrodes around your index- and middle fingers.
  • Combine the eSense Skin Response with the microphone jack of your mobile device, and with the velcro electrodes.
  • Start the app and click "Start", the measurements will begin.
  • Please carefully read the instructions within the app to get the best out of biofeedback training.
  • Have fun with the eSense Skin Response!
  • P.S. You can re-order velcro electrodes in our shop, but they are durable and can be re-used many times.


Which iOS Devices are Supported?

  • Apple® iPhone® from 4S
  • Apple® iPad® from 2nd Generation
  • Apple® iPod touch® from 5th Generation
  • Apple® iPhone 7 and iPhone 7 Plus (in combination with the included Lightning to 3.5 mm Headphone Jack Adapter)


My eSense does not work with iOS 7 (or higher)

  • The eSense works through the microphone port. From iOS 7 or higher you have to allow explicitly that the eSense app may use the microphone port, otherwise it will not work. You are asked for this during installation, please answer with “Yes” or “Allow”. After installation you can make this setting manually: Allow the eSense app to use the microphone port in the system settings of your iOS device: Settings -> Privacy -> Microphone.


Which Android Devices are Supported?

  • Android smartphones and tablets from Android 4.0

    Your Android device requires a 3,5mm jack (headphone jack) for external microphones!


Is there a way to extend the cord of the eSense?

  • If 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 3 cords that have worked:
  • 2m cord: http://amzn.to/2kJwqBM
  • 0,5m cord: http://amzn.to/2kKEONs
  • 110cm cord: http://amzn.to/2jJg1LZ
  • All three suggested cords cost between £ 6-8 and are available f.i. from Amazon. Alternatively you should be able to use other 4-pin cords as well.


Which electrodes are working with the eSense?

  • We offer 4 types of electrodes. Those have different advantages depending on the intended use. There are Velcro electrodes, Fingerclips (without gel), Gel electrodes and EDA Gel electrodes.
  • The Velcro electrodes are suitable for the beginning since they are inexpensive, re-usable and easy to use

  • The Fingerclips are suitable for the beginning as well, but more comfortable

  • The Gel electrodes have a better signal quality due to the gel, but are not re-usable

  • The EDA Gel electrodes are offering the most precise measured values and are re-usable, but require more effort in use and maintenance
