1. A skin electrode consisting essentially of:
- an adhesive electrically conductive skin-contacting member consisting essentially of a polymer component selected from the group consisting of polymerized 2-acrylamido-2-methylpropanesulfonic acid, its salts, copolymers of the acid, copolymers of the salts of the acid, and mixtures thereof, and a second component selected from the group consisting of water, alcohols and mixtures thereof, sufficient relative amounts of the polymer component and the second component being included to provide adhesiveness and flexibility to the member, andelectrical contact means connected to the conductive member for establishing electrical contact therewith.

Abstract
An improved medical electrode particularly adaptable to tape-like configurations for use in sensing and stimulation applications in which the electrode is applied to the skin. An essential electrode component comprises a mixture of a polymerized form of 2-acrylamido-2-methylpropanesulfonic acid or one of its salts with water and/or an alcohol. The mixture possesses electrically conductive properties, flexible properties and adhesive properties particularly lending itself to skin contact and adhesion.
