Abstract
A new type of electrode for measurement of dc potentials is described. Utilizing a porous graded boundary of carbon on fiber-glass wet with saline, this electrode makes possible highly drift free operation over long periods. With matched pairs of electrodes, base line drifts of less than 1 mv per hour are obtained. Examples of its use in measuring body potentials are given. The voltage-current characteristic shows a useful working region in which the electrode potential is independent of the current.
