Claim:
1. A stretchable metal wire assembly comprising: a. a first elastic substrate having a relaxed, non-stretched state, wherein the first elastic substrate is configured to be stretched along at least a first direction when a stretching force is applied along the first direction, and to return to the non-stretched state when the stretching force is removed, further wherein the first elastic substrate has a first perimeter edge and a second perimeter edge; b. a metal wire coupled to the first elastic substrate, wherein the metal wire forms a tortuous path relative to at least the first direction when the first elastic substrate is in the non-stretched state thereby enabling bending of the metal wire along at least the first direction upon application and removal of the stretching force; c. one or more adhesion joints wherein each adhesion joint fixedly attaches a portion of the metal wire to a corresponding portion of the first elastic substrate; and d. a second elastic substrate coupled to the first elastic substrate such that the metal wire is positioned between the first elastic substrate and the second elastic substrate, further wherein the second elastic substrate has a first perimeter edge and a second perimeter edge, wherein the second elastic substrate is fixedly attached to the first elastic substrate proximate the first perimeter edges of each of the first elastic substrate and the second elastic substrate, and the second elastic substrate is fixedly attached to the first elastic substrate proximate the second perimeter edges of each of the first elastic substrate and the second elastic substrate, wherein the second elastic substrate is further fixedly attached to the first elastic substrate along one or more select cross-sections extending from the first perimeter edges and the second perimeter edges, each cross-section intersecting one of the adhesion joints, thereby forming regions each bounded by the fixedly attached first perimeter edges, the fixedly attached second perimeter edges, and two fixedly attached cross-sections, within each region the first elastic substrate and the second elastic substrate are unattached and the metal wire moves freely relative to the first elastic substrate and the second elastic substrate.
