Abstract
Screen-printed and fired PZT-based films have been used as the source and detectors of elastic waves near the surface of a torsional shaft. The change in wave propagation velocity due to applied torques has bee n taken as the operating principle of a torque sensor. The new opportu nities opened by piezoelectric thick-film materials in the implementat ion of this novel sensor are demonstrated.
