    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 piezoactuator of monolithic multilayer design with an overall stack has at least one piezoelectrically active partial stack with piezoceramic layers arranged one above another and electrode layers arranged between these layers, at least one piezoelectrically inactive terminating region arranged above the partial stack, and at least one transition region arranged between the partial stack and the terminating region. The transition region has piezoceramic layers arranged one above another and electrode layers arranged between the piezoceramic layers and the piezoceramic layers and the electrode layers are arranged on one another such that there the electric fields that can be coupled into the piezoceramic layers are changed by electrical driving of the electrode layers successively in the transition region stack direction from piezoceramic layer to piezoceramic layer, and the partial stack has a safety layer towards the transition region, wherein a crack is preferably formed in the case of mechanical overloading.
