First claim
Opening claim text (preview).
The invention claimed is: 1. An electrical device, comprising: a softening polymer layer; an electrode layer on a surface of the softening polymer layer; and a cover layer composed of a second softening polymer on the surface of the softening polymer layer, wherein: a mechanical neutral plane of the device is located at or above the surface of the softening polymer layer, and an opening in the second softening polymer cover layer exposes a portion of a surface of the electrode layer, wherein the softening polymer layer and the cover layer of the second softening polymer are composed of a softening polymer having a Young's modulus that decreases by more than 1 order of magnitude within a 30° C. temperature increase. 2. The electrical device of claim 1 , wherein the cover layer has a Young's modulus that is within ±10 percent of a Young's modulus of the softening polymer layer. 3. The electrical device of claim 1 , wherein the cover layer has a thickness that is within ±10 percent of a thickness of the softening polymer layer. 4. The electrical device of claim 1 , wherein the within 30° C. temperature increase is from a lower temperature of 20° C. to a higher temperature of 50° C. 5. The electrical device of claim 1 , wherein the within 30° C. temperature increase is from a lower temperature of 20° C. to a higher temperature of 37° C.
