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.
Claims26
A piezoelectric multi-layer component comprising:
- a plurality of ceramic layers, and
- one or more electrode layers having 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.
A piezoelectric multi-layer component, comprising:
- a plurality of ceramic layers having a first mechanical tensile strength;
- and
- one or more electrode layers at least partially surrounded by the plurality of ceramic layers and having a material structure having a second mechanical tensile strength,
- wherein the material structure is changed relative to the plurality of ceramic layers and reduces the second mechanical tensile strength to less than the first mechanical tensile strength.
