    摘要： A piezoceramic multilayer actuator (10) has a plurality of piezoceramic layers (12) and a security layer (20) disposed between two piezoceramic layers (12). The piezoceramic layers (12) have a piezoceramic first material sintered at a sintering temperature. The security layer (20) has a second material (32) and particles (30) at least partially embedded in the second material (32). The particles (30) have a third material different from the first material and different from the second material (32). An adhesion between the third material and the first material is weaker than an adhesion between the second material (32) and the first material.

    摘要： A piezoelectric component with a monolithic stack has piezoceramic layers and electrode layers arranged alternately one on top of the other, at least one porous security layer arranged in the stack for the formation of a crack if mechanical overload of the stack occurs, at least one outer electrode arranged at a lateral surface section for electric contacting of the electrode layers and a plastic sheath of the stack for protecting the stack, wherein the plastic sheath has silicon. The piezoelectric component is characterized in that a coating of the outer electrode, has silicon-free polymer, is arranged between the outer electrode and the plastic sheath. By coating the plating of the outer electrode, the area of the security layer present directly under the plating is protected from silicon component deposits. The piezoelectric component is used for the control of valves, particularly of injection valves of internal combustion engines.

    摘要： A method for producing a piezo actuator includes: providing a green stack including alternately successive green films and inner electrode layers; forming trenches on the outside green stack in areas in which the inner electrode layers are intended to be electrically insulated from the corresponding outer electrodes, the trenches shortening the inner electrode layers from the outside of the green stack toward the inside; filling the trenches with an electrically insulating slurry; further processing the green stack, including filling the trenches with slurry, such that the green films produce piezo electric layers and the green stack produces a piezo stack; mounting two outer electrodes on the outside of the piezo stack, such that the two outer electrodes are alternately electrically connected to the inner electrode layers. The trenches may be filled with the slurry using one of the following methods; screen printing, immersion, spraying, or vacuum infiltration.

    摘要： A piezoelectric stack (1) has alternately successive piezoelectric layers (2) and inner electrode layers (3, 4) which are alternately electrically connected to two outer electrodes (7, 8) which are arranged on the outer side (5, 6) of the piezoelectric stack (1). The piezoelectric stack (1) also has at least one safety layer (9, 40, 50) which is arranged between two successive piezoelectric layers (2) instead of one of the inner electrode layers (3, 4). The safety layer (9, 40, 50) is structured in such a manner that it has an internal interruption (13, 44, 45, 53) which is configured in such a manner that the safety layer (9, 40, 50) does not form an electrical contact between the two outer electrodes (7, 8) if it contact-connects both outer electrodes (7, 8) and is electrically conductive.

    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 behavior similar to the multilayer actuator (1) without poling cracks.
