ABSTRACT:
A transducer includes an elongated piezoelectric sensor having only a single integrated mass of piezoelectric material and a pair of relatively longer opposite edges and a pair of relatively narrower opposite edges. The transducer also includes a sensor support. The support imposes less constraint on one of the pairs of edges than on the other pair. Two piezoelectric sensors are supported back-to-back. Each of the sensors is held on opposite edges by a pair of opposite ledges, while two other opposite edges of the sensors are less constrained. The maximum displacement of the two less constrained edges of each sensor are limited by another pair of opposite ledges which are tapered or spaced away from the sensor when the sensor is in its normal position.
