Abstract:
The transducers active elements are a plurality of thin, narrow, piezoelectric bars bonded side-by-side to a flexible plate. Electircally, a circuit is coupled across the thickness of each bar or strip to include the bars as a plurality of parallel capacitors. The plate has a fixed length that is maintained during operation. Consequently, piezoelectric length expansions and contractions of the bars are translated into an oscillating bending motion of the bars and the plate for transducing purposes. Author
