A transducer has a thick perimeter and an integral diaphragm extending across said perimeter, all formed of a thermoplastic resin. A thick mass is molded at the center of the diaphragm. Resistive elements formed of a conductive polymer are printed and baked on the diaphragm to form a Wheatstone bridge. The transducer is used as an accelerometer or load cell.
