Abstract
A three-dimensional inductive charging coil assembly and a method of making the same. The method can include patterning a first conductive layer affixed to a first surface of an insulating layer to form a coil configured to transmit or receive power, patterning a second conductive layer affixed to a second surface of the insulating layer opposite the first surface to form a conductive trace element, and electrically coupling the coil and the conductive trace element. The coil, insulating layer, and conductive trace element can be molded (e.g., simultaneously) into a three dimensional shape. In some embodiment, the molding can include a thermoforming process such as compression molding, vacuum forming, or the like.
