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 piezo actuator in a monolithic multilayer design, has at least one piezoelectrically active stack element, wherein the stack element has stacked piezoceramic layers made of piezoceramic material and electrode layers arranged between the piezoceramic layers, at least one piezoelectrically inactive terminating region arranged above the stack element, and at least one junction region arranged between the stack element and the terminating region, wherein the stack element, the terminating region and the junction region are connected to one another to form a monolithic total stack. The junction region has stacked piezoceramic layers and electrode layers arranged between the piezoceramic layers, and the piezoceramic layers and the electrode layers are in a form and are arranged on one another such that in the stack direction of the junction region one piezoelectrically active area per junction piezoceramic layer is successively changed from piezoceramic layer to piezoceramic layer.

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： A piezoelectric component, e.g., for use as an actuator of a fuel injection valve in a motor vehicle, may include a stack-shaped actuator body including a plurality of piezoelectric elements and inner electrode layers arranged in an alternating manner in a stacking direction, each inner electrode layer being connected alternately to one of two metalizations on an outer face of the stack in an electrically conductive manner. Each metalization is connected to an electrically conductive electrode structure via an electrically conductive contacting element (e.g., adhesive or solder). The stack-shaped actuator body has at least one predetermined breaking point, and the metalizations and/or the contacting elements have a recess in the region of the at least one predetermined breaking point.
