[57] ABSTRACT
A body electrode comprising one or more galvanically active sensors, a first layer capable of adhering to the skin on the body contact side and a non-adhesive covering second layer on the side of said sensors opposite the body contact side. The first layer comprises an electrically conducting adherent, elastic hydrophilic material. The body electrode is characterized by the fact that the first layer and the second layer have been produced by mold casting. The chief advantage of such electrodes is the fact that they may be produced by casting in a simple and cost-effective manner, thus avoiding stamping processess.
