Biosensor with pressure compensation
First Claim
1. An apparatus for measuring physiology comprising:
- a pair of electrodes;
one or more pressure sensing devices attached to one or more of each of the pair of electrodes;
circuitry configured to evaluate electrodermal activity of skin to which the pair of electrodes contacts; and
circuitry configured to compensate electrodermal activity evaluation based on force applied to the pair of electrodes.

Abstract
A biosensor is described which can obtain physiological data from an individual. The biosensor may collect electrodermal activity, skin temperature, and other information. The biosensor may be attached to the body through the use of a garment which may be fastened in multiple locations on the human body. The biosensor includes compensation for electrodermal activity measurements based on the amount of pressure applied to the electrodes that are in contact with the skin. As pressure is increased the electrodermal activity values typically increase. By compensating for the influence that pressure changes have on electrodermal activity, more accurate analysis of physiology and therefore mental state analysis may be performed.
