Properties of electrode used in electrodermal measurement.

Abstract

Various types of electrodes frequently used in electrodermal measurements are shown to have properties which might contribute sizeable errors to the measurements obtained. Electrical resistance of the skin is shown to be an inverse function of the effective electrode area and to be constant for 5 voltages ranging from 1.5 to 7.5 and for 5 currents in the range of 10 to 200 ma. The design of a more nearly ideal electrode is described together with a formal for zinc sulphate electrode paste. From Psyc Abstracts 36:02:2DA29L.
