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 film for electrically interfacing to said patient's skin, the liquid film being electrically and mechanically connected to said conductive member. The non-liquid 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 15 to 30 pph acrylic acid, 0.5 to 30 pph N-vinylpyrrolidone and 0.01 to 2 pph of a crosslinking agent. The monomeric mixture may further comprise from about 0.5 to 8 pph of a thickening agent comprising a N-vinylpyrrolidone/acrylic acid copolymer.
