Integrated compliant boundary for piezoelectric bimorph actuator

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). 本申请涉及种具有体柔性边界的压电双晶片执行器(16)，该压电双晶片执行器(16)使用第压电元件(22a)、第二压电元件(22b)和复合层(20)，该复合层(20)紧密啮合在第压电元件(22a)和第二压电元件(22b)之间以形成双晶片执行器(16)。复合层(20)从压电元件(22a，22b)外围的边缘延伸，并且具有弯曲的接合部分(24)，所述弯曲的接合部分(24)为附接双晶片执行器(16)提供底座。
