Abstract
A strain gauge or transducer is provided incorporating a supported film electrical resistance element whose electrical resistance varies as a function of applied mechanical strain and is provided with electrically conductive terminals. The resistance element comprises a dispersion of electrically conductive or resistive particles in an organic polymer together with an optional electrically insulating filler material. In a particular embodiment, the resistance element is supported on a member of anodized aluminum.
