Mindfield® eSense Skin Response

eSense Skin Response biofeedback device

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.)

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!

The app for eSense is free, and allows exporting the measured data via e-mail.


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, theraputic 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 ecample, mental activity, emotional arousal, deep inhalation or fright.

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

A detailed introduction is included in the free app.

  • Apple® iPad® from 2nd Generation
  • Apple® iPod touch® from 5th Generation


Which other 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:
  • 0,5m cord:
  • 110cm cord:
  • 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.


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.
