Abstract
In the embodiments described in the specification, a piezoelectric transducer has electrodes to the piezoelectric layer with an adhesive bonding agent under pressure applied hydraulically so as to be distributed uniformly throughout the surface of the piezoelectric layer. In one embodiment the dielectric film also carries conductor arrays for connecting the electrodes to remote driver chips at locations spaced from the surface of the piezoelectric layer.
