Piezoelectric multi layer component particularly bending transducer or multilayer actuator, has piezoelectric layer with front side and rear side and electrode surface is oppositely arranged on front and rear side of piezoelectric layer

摘要

The piezoelectric multi layer component has a piezoelectric layer (10) with a front side (20) and a rear side. An electrode surface (30) is oppositely arranged on the front and rear side of the piezoelectric layer. One of the electrode surfaces has a closed inner surface (40) and an open marginal surface (50) which partly surrounds the inner surface so that a transition area (60) is positioned between a piezoelectrically active area (70) and a piezoelectrically inactive area (80) in the piezoelectric layer. Independent claims are also included for the following: (1) a multi layer component has an edge surface, which has a net like structure (2) a method for production of a piezoelectric multi layer element.
