    摘要: In a piezoelectric multilayer actuator (1) having micromechanical relief zones (30) and an insulation layer (40) as well as in a method for producing said actuator, as a result of the micromechanical relief zones (30), poling cracks are concentrated in these relief regions (30). This makes it possible to provide the sections I, II, III of the multilayer actuator (1) with an insulation layer (40) which only has an extension behaviour similar to the multilayer actuator (1) without poling cracks.

    摘要: In a method of manufacturing a piezoceramic multilayer actuator (10), a plurality of green layers is provided, 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).
