Abstract: A stretchable conductor includes a substrate with a first major surface and an elongate wire, wherein the substrate is an elastomeric material, the elongate wire is on the first major surface of the substrate, the wire includes a first end and a second end, and further includes at least one arcuate region between the first end and the second end. At least one portion of the arcuate region of the wire in the region has 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. The unembedded second surface portion of the arcuate region may lie above or below a plane of the substrate. Additionally, different methods of preparing said stretchable conductor are disclosed. Composite articles including said stretchable conductor in durable electrical contact with a conductive fabric are also disclosed.
