Abstract: A dry electrode for the detection of biopotentials existing on the surface of the skin of a living body, including a non-polarizable dry electrode pad having opposed adhesive surfaces, one of which is adapted to engage the skin of the living body and extend ionic charge conduction from the body to the surface of a non-polarizable electrode interface within the pad. An electrically conductive contact makes electrical and mechanical connection from the electrode pad to a wire or electronic amplifier by means of a second adhesive surface on the electrode pad. In a preferred embodiment, conductive adhesive layers are applied to opposed sides of a conductive foam pad to construct the dry electrode pad.
