1. 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 wire comprises a plurality of braided metal wire strands, further wherein the elastomeric material occupies an interstitial region between the braided metal wire strands.
