摘要：
A piezoelectric actuator includes a cantilever membrane. A thin film sheet is affixed to one side of the cantilever membrane to bend the membrane in multiple directions in response to an electric field induced within the thin film sheet. A plurality of coplanar electrodes disposed on the thin film sheet are interdigitated in relation to one another to generate the electric field during application of a voltage across interdigitated electrodes.
