Tape electrode
First Claim
1. A solvent activated conductive dry tape electrode for prolonged adhesion to the epidermal layer of the skin of a human which is readily activated and adherable with the application of a non-aqueous solvent comprising, a highly porous tape substrate, a conductive coating positioned on one surface of the substrate, said coating including a mixture of skin compatible metal particles blended into a water insoluble low tack adhesive matrix in an amount sufficient to supply electrical continuity between the metal particles with said adhesive matrix being non-toxic and non-irritating and including a non-allergenic polymer that is at least partially soluble in a volatile organic solvent, the adhesive matrix coating having a thickness such as to permit permeation of a water vapor generated on the surface of the skin through the coating layer and tape substrate, and a further coating including a mixture of said conductive coating and a magnetic material in which the conductive coating has the water insoluble adhesive matrix and metal particles to provide the electrical continuity between the particles and with the magnetic material being mixed in amounts sufficient to provide magnetic continuity between the magnetic particles, said further coating being applied to one surface of the substrate and separated from the conductive coating in a position to allow electrical continuity to exist between said coatings when the electrode is activated.

Abstract
A tape electrode usable for the transmission of electrical signals into the human body through the skin. The electrode is flexible in construction so that it may be applied to the skin to secure good electrical contact therewith and remain in place for extended periods despite movement, perspiration and the presence of water on the skin surface. The tape construction includes a surface of a conductive material combined with an adhesive on one surface and the conductive material with a magnetic powder on the second surface together with a coupler through a permanent magnet or magnetic substance to which a lead wire is connected to effect electrical connection through the conductive material in the adhesive and retain the lead wire in position through the magnetic attraction of the permanent magnet to the magnetic material.
