Abstract
Flexible electrical devices comprising electrode layers on softening polymers and methods of manufacturing such devices, including lift-off processes for forming electrodes on softening polymers, processes for forming devices with a patterned double softening polymer layer, and solder reflow processes for forming electrical contacts on softening polymers.
Claims5
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.
