  • Piezoelectric component with predetermined breaking point and method for manufacturing and using the component
    Publication number: 20060181178
    Abstract: A piezoelectric component (1) has at least one monolithic piezo element (10) having an electrode layer (101), at least one further electrode layer (102), at least one piezoceramic layer (103) disposed between the electrode layers and at least one predetermined breaking point (100) which, in the event of mechanical overload of the piezo element, leads to the formation of a specific crack (110) in the monolithic piezo element, wherein the predetermined breaking point includes the electrode layer. The component is, for example, a piezoelectric actuator with a monolithic actuator body (2) in which piezo elements with predetermined breaking points and further piezo elements (11) without predetermined breaking points are arranged one on top of the other and sintered collectively.
