Skin resistance
The skin resistance is the measure of the electrical conductivity of the skin . The reciprocal value is called the skin conductance . The skin resistance is part of the body resistance .
The skin conductivity is primarily influenced by the activity of the sweat glands. The sweat secretion is controlled by the vegetative nervous system and is therefore deliberately not influenced, or only indirectly through special, learnable techniques. If sweat is produced, the skin's ability to function as a conductor increases, and so does the skin conductance.
Skin resistance is measured, for example, as part of biofeedback training, lie detectors and psychophysiological experiments in order to measure the state of arousal in relation to a specific stimulus, see also electrodermal activity (psychogalvanic skin reaction).
