摘要： A piezoceramic multilayer actuator (10) includes a plurality of green layers, wherein the green layers are to be converted to piezoceramic layers (12) with a piezoceramic material in a subsequent step of heating. A security layer material mixture with a second material (32) and particles (30) embedded in the second material (32) is provided, wherein the particles (30) have a third material different from the first material and different from the second material (32). The security layer material mixture is laminated between two piezoceramic layers (12), thereby forming a green stack. The green stack is heated to a sintering temperature, wherein the green layers are converted to the piezoceramic layers (12), and wherein a chemical reaction of the third material degrades the mechanical connection of the piezoceramic layers (12) by the security layer (20).

摘要： A flat multilayered component for use as an actuator or a sensor, is described. The flat multilayered component contains a layer of electrically activatable material, a passive middle layer disposed adjacent the layer of electrically activatable material, and a further passive material layer disposed adjacent the passive middle layer. The passive middle layer has a higher coefficient of linear thermal expansion than both of the layer of electrically activatable material and the further passive middle layer.
