Multilayer piezoelectric actuator

摘要

A piezoelectric multilayer actuator has a hexagonal cross-section and a housing of circular cross-section. An Independent claim is also included for production of the above piezoelectric multilayer actuator by stacking and compacting green bodies provided with electrode structures (20) on their top faces, sawing to obtain one or more piezoelectric elements of hexagonal cross-section and introducing the or each element into a housing of circular cross-section. Preferred Features: The actuator has electrodes (2) of AgPd and piezoelectric layers of PbTiO3, PbZrO3 or PZT.
