Classification: CPC B  H  Y | IPC H

Claim 10:
11. A stretchable conductor comprising:
a substrate with a first major surface, wherein the substrate comprises an elastomeric material,
an elongate wire on the first major surface of the substrate, wherein the wire comprises a first end and a second end, and wherein the wire comprises at least one arcuate region between the first end and the second end, optionally wherein the wire comprises a metal, and
wherein at least one portion of the arcuate region of the wire in the region comprises a first surface area portion embedded in the surface of the substrate and a second surface area portion unembedded on the substrate and exposed in an amount sufficient to render at least an area of the substrate in the region electrically conductive,
wherein the stretchable conductor further comprises:
a second elongate wire on a second major surface of the substrate opposite the first major surface, wherein the second wire comprises a first end and a second end, and wherein the second wire comprises at least one arcuate region between the first end and the second end, wherein at least one portion of the at least one arcuate region of the second wire comprises a first surface area portion embedded in the surface of the substrate, and a second surface area portion unembedded in the surface of the substrate and exposed in an amount sufficient to render at least an area of the substrate in the at least one arcuate region of the second wire electrically conductive;
a first layer of stretchable conductive film in contact with both the first wire and the first major surface of the substrate; and
a second layer of stretchable conductive film in contact with both the second wire and the second major surface of the substrate; wherein
the first layer of stretchable conductive film and the second layer of stretchable conductive film are in electrical contact with each other.
