Galvanic Skin Response (GSR)

Galvanic Skin Response (GSR) measures changes in sweat gland activity on the skin as an indication of physiological or psychological arousal.

Galvanic Skin Response may also be referred to as electrodermal response (EDR), skin conductance response (SCR), electrodermal activity (EDA), electrodermal level (EDL), or skin conductance level (SCL).

Using PowerLab as the foundation of your data acquisition solution, you can use a galvanic skin response sensor to record and analyze the electrical conductance of the skin against a broad range of other physiological or psychological signals in real-time. Integrate multiple data streams and easily apply calculations and plots with LabChart software to discover powerful connections between skin conductance response level and physical or emotional stimuli.

Human eccrine sweat glands, present on the palmar surfaces of the hands and bottoms of the feet, are innervated by the sympathetic branch of the autonomic nervous system (ANS). These glands respond readily to a person’s mental and emotional state are are often more responsive than other variables such as skin temperature.
The human eccrine glands act as variable resistors. When the eccrine glands fill with fluid, the skin resistance decreases and the conductance increase. Consequently, it is possible to measure skin conductance by placing two electrodes on the fingers of human subjects. The measured parameter, know as skin conductance, is expressed in microsiemens (µS). Microsiemens are a common unit of conductance.
