Piezoelectric actuator of lamination type |
摘要 |
A piezoelectric actuator of a lamination or stack type has a plurality of sheet-like electrostrictive elements and oppositely poled electrode layers provided on the major surfaces of the each element, respectively, each electrode layer being arranged so as to define an insulating zone on the one end portion of the associated major surface. An insulating gap is formed between the adjacent elements by the insulating zone(s) and is filled with an elastic material.
