An article of manufacture having an in-molded resistive and/or shielding element and method of making the same are shown and described. In one disclosed method, a resistive and/or shielding element is printed on a film. The film is formed to a desired shape and put in an injection mold. A molten plastic material is introduced into the injection mold to form a rigid structure that retains the film.

Sensors incorporating piezoresistive materials are described. One class of includes conductive traces formed directly on or otherwise integrated with the piezoresistive material.
