Abstract

Piezoelectric transducers for high power applications are detailed that comprise a plurality of piezoelectric layers (18, 20) and a plurality of shims (30, 32) that are in a sandwich structure, and in which the shims (30, 32) extend substantially beyond the piezoelectric layers. The shims may also function as electrodes and they provide the cooling means for the transducers.
