Silver-silver chloride electrode and electrical circuit

Abstract

A silver-silver chloride electrode contains silicone rubber as a binder in which silver powder, silver chloride powder and silica powder are dispersed. A current density of a current flowing through an electric circuit is equal to or greater than 0.64 μA/mm2 after 5 minutes from the beginning of voltage application to the electric circuit when the electric circuit in which two silver-silver chloride electrodes and a phosphate buffered saline are connected in series is made up of the two silver-silver chloride electrodes and the phosphate buffered saline containing no calcium and no magnesium interposed between the two silver-silver chloride electrodes.
