Abstract
Various implementations include a self-heating device. The device includes an electrically insulative layer, an electrically conductive layer, a first electrode, and a second electrode. The electrically insulative layer has a first surface and a second surface spaced apart from the first surface. The electrically conductive layer has a first surface and a second surface spaced apart from the first surface. The second surface of the conductive layer is coupled to the first surface of the insulative layer. The conductive layer includes a polymer. Conductive nanoparticles are embedded in the polymer. The first electrode and a second electrode are coupled to the conductive layer. The first electrode and the second electrode are spaced apart from each other and in electrical communication with each other through the conductive layer. The conductive layer produces heat through Joule heating when electrical current is passed through the conductive layer.
