ABSTRACT:
The present invention provides a method of manufacturing piezoelectric transducers that improves performance by reducing the mechanical losses in the component interfaces. The method involves the epoxy impregnation and encapsulation of the components within the piezoelectric stack assembly. Impregnation is achieved by capillary action that results in a chemical bond. The encapsulation method results in an epoxy conformal coating that provides a high degree of protection from harsh operational environments and reduces the risk of high voltage electric breakdown.
