SILVER‐SILVER CHLORIDE ELECTRODERMAL ELECTRODES

Abstract

ABSTRACT An electrolytic method is presented for the preparation of a disc type Ag‐AgCl electrode which has low bias potential and drift, moderate resistance and low polarization, is relatively durable, and can be easily replated if damaged or contaminated. The electrode has been used for measuring both skin potential and conductance and is compatible with a previously published device which compensates for non‐isothermal electrodes in skin potential recording. Although other applications have not been explored, the general design might be useful for the recording of other peripherally assessed bioelectric activity as well. A convenient electrode paste is described which does not dry out quickly and can be stored indefinitely.
