Skin Conductance Sensor (GSR)

The GSR Sensor measures sweat gland activity at the fingers or in the palm of the hand. Skin Conductance (SC) is also known as galvanic skin response (GSR) or electrodermal activity (EDA). The sensor comes with Ag-AgCL velcro straps snap-on electrodes, which can be used over 100 times. The electrodes are attached to the fingers of the non-dominant hand. 

Skin conductance is expressed in microsiemens. Sweating is controlled by the sympathetic nervous system and this response is closely related to arousal. The sensor has been designed to measure minute (1/1000) micro-siemens relative changes in sweat activity.

The GSR Sensor for NeXus offers:

• Adjustable velcro straps for every size finger
• Easy snap-on leads
