Electrically conductive compositions particularly useful for biomedical electrodes wherein the conductive composition comprises the physical and electrical interface between the electrode and the skin of a subject. The conductive composition is conformable, flexible, adhesive and forms a cohesive body readily adaptable to use at the interface area of the electrode. The compositions comprise (1) an interpenetrating polymer network consisting essentially of a hydrophyllic crosslinked polymer formed from a water soluble monomer and a hydrophyllic, polymer which is not crosslinked, (2) a humectant, and (3) water.
