The eSense is a small sensor to measure your skin conductance through two electrodes and the microphone input of your iPhone (3G), iPad (from the first-gen) and iPod touch (from the fourth-gen). A free application is included to illustrate your skin's conductance in different ways. You can export the values via email and have different biofeedback training possibilities.
Identify your level of inner stress and improve it with biofeedback. Your skin response responds to less excitement and can be trained to significantly improve relaxation.
Galvanic response from Pele / Conductance Skin
Known as galvanic skin response (GSR) , the electrodermal response (EDR) or skin conductance (SC) is a measurement method of conductance electrical of the skin, which varies with your level humidity. Conductance is measured in Siemens by skin response. Two electrodes are attached to the finger gauge and medium , not too tight to squeeze the blood, but also not too loose to keep them in position. The electrodes must not move and the hand should be relaxed.
The eSense measures the electrical conductance (which is the reverse of electrical resistance), between 2 points , and is essentially a type of ohmmeter. Active measurement, involves sending a very small amount of current through fingers.
The glands of the skin are felt by sympathetic nervous system and only are a good indicator of a stress level internal and activation. This aspect can be demonstrated during measurement by confrontation with a stimulus as the mental activity, emotional stress , deep breathing or a unexpected noise loud. A skin response must increase as a skin becomes moistened.
To get a good measure keep room temperature constant, breathe relaxed ( not too deep) and do not move the hand with the electrodes.
Reduce your stress level effectively com eSense , in m everywhere with your device iOS!
How to use the skin response eSense?
With the purchase from eSense you can download our free application on the App Store by Apple ®. (you can also do this before, but without a sensor do app will deliver values meaningless)
Connect the electrodes to yours middle and part of the index finger upper.
Connect eSense to yours microphone input device iOS.
Start the application , read the instructions included and start using eSense!
