Abstract :
Dry skin resistance is measured by application of a positive direct current flowing from a dry electrode to the skin. A device for finding low-resistance points is proposed, and methods for measuring the distribution of skin resistance are discussed. The voltage ratio is used to find the low-resistance points, using both a constant-current and a constant-voltage method. The latter is shown to be particularly effective. Guidelines for optimal design of the device are proposed.
