Skin Conductance

Skin conductance is a measure of sweat gland activity, where skin resistance to electric current is used to detect changes in physiological arousal. It is commonly used to measure emotional and cognitive responses and has applications in user experience research, psychology, and medicine. Skin conductance has become an important tool in the study of emotional states, allowing the response to a stimulus to be quantified and compared to the emotional state of an individual before and after the stimulus. Additionally, it has been used to help detect heart rate variability to diagnose sleep apnea.
