Abstract

A biomedical electrode (10) adapted to be applied to a body and adapted to be electrically and mechanically connected to an electrical lead wire (14). The electrode (10) contains a protective, electrically insulative web 12) and an adhesive (16) adjacent one side of the web (12) which is adapted to be oriented to the body. A release liner (18) is placed between the web (12) next to adhesive (16) to facilitate removal and placement of an electrical lead wire (14). An electrically conductive film (22) is positioned adjacent the adhesive (16) opposite the release liner (18). Finally, another layer of adhesive (24) which is electrically conductive is positioned adjacent the electrically conductive film (22) opposite the layer (16of adhesive, which electrically conductive adhesive (24) is adapted to be applied to a body. Alternatively, the electrode (10) has a metallic coating (34) applied to the bottom side of a protective, electrically insulative web (32). A release line (18) separates the metallic coating (34) of the protective web (32) from an electrically conductive adhesive (24) which is adapted to be applied to a body.
