a cohesive nonsticky electrically conductive gel is disclosed , for facilitating low resistance contact between a metal electrode and a biological body . the gel comprises an aqueous solution of up to saturated concentrations of ionized salts as the conducting agent , a natural gum capable of crosslinking , and a crosslinking material which provides the electrically conductive gel with sufficient internal strength to remain cohesive without reinforcement . the gel has good electrical characteristics and improved physical properties which prevent the gel from leaving a messy residue on the skin of the patient or on the electrode .
