Abstract: An electrical device, comprising a softening polymer layer, an electrode layer on a surface of the softening polymer layer and a cover polymer layer on the surface of the softening polymer layer. An opening in the polymer cover layer is filled with a reflowed solder, one end of the reflowed solder, located inside the opening, contacts a contact pad site portion of the electrode layer, and another end of the reflowed solder contacts an electrical connector electrode of the device.

Abstract: A nerve cuff electrode device comprising a cuff body having a smart memory polymer layer with a rigid configuration at room temperature and a softened configuration at about 37° C. The smart memory polymer layer has a trained curved region with a radius of curvature of about 3000 microns or less. A plurality of thin film electrodes located on the smart memory polymer layer. The thin film electrodes include discrete titanium nitride electrode sites that are located in the trained curved region. An exposed surface of each of the discrete titanium nitride electrode sites has a charge injection capacity of about 0.1 mC/cm2 or greater. Methods or manufacturing and using the device are also disclosed.

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.
