ABSTRACT:
An electrode providing electrical contact with a patient's skin includes a conductive member adapted for connection to an external electrical apparatus and a non-liquid water containing film for electrically interfacing to said patient's skin, the non-liquid film being electrically and mechanically connected to said conductive member. The non-liquid water containing film includes an electrically conductive organic polymer plasticized with a polyhydric alcohol with said organic polymer being derived from a monomeric mixture comprising from about 2 to 30 pph acrylic acid, 2 to 30 pph of a glycolvinylether and 0.01 to 1.5 pph of a crosslinking agent. Preferably the polyhydric alcohol is glycerol.
