Abstract
A bioelectrical electrode is disclosed consisting of metal on its skin-side contact surface and having a conductive adhesive layer covering at least part of the skin-side contact surface. The conductive adhesive layer is formed as a layer of an aqueous dispersion adhesive that is pressure-sensitive and contains a substance that dissociates in aqueous solution. The preferred adhesive layer comprises an aqueous dispersion of a thermoplastic acrylic resin and gelatin. The preferred dissociating substance is MgCl.sub.2 and the preferred metal contact surface is zinc. The adhesive layer may additionally contain citric acid.
