Abstract
Abstract A process for manufacturing a body electrode is provided. The body electrode includes one or more galvanically active sensors which are combined with a first layer capable of adhering to the skin on the body contact side of said sensors and a second layer on the side of said sensors opposite the body contact side. The first layer comprises an electrically conductive, adherent, elastic hydrophilic material. The second layer is a covering or supporting layer and comprises an elastic non-adherent material. According to the present invention, the layer adhering to the skin and the covering or supporting layer are cast in a mold during manufacture of the electrode. This process eliminates the problems encountered with the prior art stamping process, especially in stamping the conductive layer which adheres to the skin.
