UN PROCÉDÉ DE FABRICATION D'UN ACTIONNEUR BIMORPHE PIÉZOÉLECTRIQUE AVEC UN LIMITE ÉLASTIQUE INTÉGRÉE

摘要

A piezoelectric bimorph actuator (16) with an integral compliant boundary employs a first piezoelectric element (22a), a second piezoelectric element (22b) and a composite layer (20) intimately engaged between the first and second piezoelectric elements (22a, 22b) to form a bimorph actuator (16). The composite layer (20) extends from a peripheral edge of the piezoelectric elements (22a, 22b and has a curved interface portion (24) providing a mount for attachment of the bimorph actuator (16).
