Piezoelectric component and method for the production thereof

摘要

A piezoelectric component includes piezoelectric layers and electrode layers between at least some of the piezoelectric layers. The electrode layers define a middle segment in an interior of the piezoelectric layers and end segments located between ends of at least some of the electrode layers and an end of at least one of the piezoelectric layers. The piezoelectric layers include a first piezoelectric material at the end segments and a second piezoelectric material at the middle segment between electrode layers. The first piezoelectric material has a first expansion that is less than a second expansion of the second piezoelectric material.
