Abstract

A piezoelectric multi-layer component is described herein. The component includes a plurality of ceramic layers, and one or more electrode layer. The one or more electrode layer has a material structure that is different than the plurality of ceramic layers and is configured to at least partially block a propagation in a longitudinal direction of pressure waves acting on the piezoelectric multi-layer component.
