Product Code: 2703-EDA
Electrodermal Activity (EDA) Sensor Electrodermal Activity (EDA) Sensor
Electrodermal Activity (EDA) can be defined as a transient change in certain electrical properties of the skin, resulting from sweat secretion and sweat gland activity. These changes can result from elicited or natural stimuli that trigger a regulatory response by the sympathetic nervous system.
 
The Electrodermal Activity (EDA) is capable of accurately measuring the skin activity with high sensitivity in a miniaturized form factor. The low-noise signal conditioning and amplification circuit design provides optimal performance in the detection of even the most feeble electrodermal skin response events.
