  • Patent number: 4377170
    Abstract: A non-polarizable electrode is disclosed comprising a metallic sensing element in contact with an electrolyte gel or other conformable, electrically conductive skin-interfacing material containing dissolved electrolyte salt and an oxidizing agent. The oxidizing agent reduces the metal on the surface of the sensing element to a metal cation which reacts with the anion of the electrolyte salt to produce an insoluble compound which is deposited on the sensing element to render it non-polarizable. The preferred embodiment of the invention relates to silver/silver chloride electrodes.
