Abstract
Abstract An electrode sensor for a biomedical electrode of the button type comprises a plastic base which consists of a shank to be clinched to fill up the cavity of an expanded hollow head of an electrode button and a base flange formed in one piece of the shank, and an electrically conductive film formed over the plastic base. The flange is bowl-shaped with a gradual upward inclination from the center toward the periphery. The flange has a plurality of projections or grooves formed on at least either its upper or under side.
