A trial equipment to measure skin conductance, based on the recommendations of The Society for Psychophysiological Research

Abstract

It has been recommended by The Society for Psychophysiological Research (USA) that skin conductance should be recorded by the application of constant voltage 0.5V across the electrodes, and the resultant current should be measured by the amplification of potential across a small resistor in series with the skin. A simple and inexpensive circuit has been recommended for this purpose. However, we cannot afford the same circuit in Japan, since the reference diode LM 113 T is not available. A Japanese version for this purpose is proposed, with satisfactory results.
