 Electrochemical skin conductance

Electrochemical skin conductance (ESC) is a biomarker used to measure the electrical properties of the skin, specifically its conductance. It reflects the activity of sweat glands and can provide information about an individual's physiological and emotional state. The measurement is typically obtained using electrodes placed on the skin, which detect changes in the electrical conductance resulting from the presence of sweat. ESC is often linked to the body's autonomic nervous system responses, particularly in relation to stress, arousal, and emotional states.
