Abstract
A low-impedance biological electrode device for establishing electrical connection between the human body and electrical recording or stimulating apparatus without the use of conducting fluids, such as, gels, pastes and electrolytes, comprising, a substantially planar relatively thin electrode body, having as the electrically conducting connecting unit contacting the human body, a plurality of individual longitudinally extending strands, fibers, or filaments of conducting material embedded in a pressure-sensitive or solvent-activated adhesive which serves to bond the strands together in a composite connecting unit and to bond the connecting unit on one side to said electrode body and on the other side or interface to the human body, a modification being the use of strands cross-oriented with respect to the longitudinal strands, as exemplified by woven conductive material, the connecting unit being provided with a transverse bus bar in the form of metal foil in electrical contact with an electrical connecting element for conducting current from the connecting unit in contact with the human body to the electrical recording or stimulating apparatus.
