GSR + Respiration Biofeedback for mobiles

The 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, from home with just your smartphone or tablet.

The Importance of Breathing in Stress Relief

Our breathing can be influenced by our minds and is the most widely used relaxation technique worldwide to counteract and actively reduce stress. Direct biofeedback of the respiration, ie the real-time feedback of the breathing pattern, the depth of breath and the respiratory rate, helps our consciousness to learn new and better breathing patterns more quickly and to implement them. The biofeedback training helps to concentrate fully on the breathing, especially for beginners this is a great help. Through a breath back feedback this entry is much easier. In addition to this measurement and feedback, the eSense app also offers so-called respiratory aids, where you can specify how to breathe.


Importance of biofeedback breathing training

Two main measures are critical in measuring respiration: respiratory amplitude (RA = respiration amplitude, how deep you breathe) and the rate of respiration, the breaths per minute. Breathing is a parameter that we can consciously control. Many other typical biofeedback parameters do not have this option and can only be controlled vegetatively. Therefore biofeedback breathing training is an optimal biofeedback training variant especially for beginners.

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.
