Mindfield® eSense

The Mindfield® eSense Skin Response is a small sensor to measure your skin conductance using two electrodes and 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.

A free app is included to display your skin conductance in multiple ways. You can export the measured data via e-mail.




Skin Response / Skin Conductance

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 two adjacent fingers. Active measurement involves applying a very low, unnoticeable voltage to the fingers.


Using the eSense Skin Response

It’s easy!

  1. After buying the eSense Skin Response, please download our free app from the App Store (Apple) or Google Play (Android). You can download and try the app without the sensor. (The app will deliver meaningless values in this case.)
  2. Connect the electrodes to the pads of your middle and index fingers.
  3. Connect the eSense Skin Response to the microphone input of your device.
  4. Start the App, read the included training instructions and start using your eSense! To get the most precise measurement, work at a relatively constant ambient temperature, breathe calmly (not too deep) and do not move the hand with the electrodes too much.
  5. Have fun!
  6. P.S. You can order more electrodes here, but they will last a while with normal usage.
