摘要： A piezo actuator has a stack element and at least one further stack element, wherein each of the stack elements has stacked piezoceramic layers and electrode layers arranged between the piezoceramic layers, each of the electrode layers extends to at least one of at least two lateral surface sections of the stack element which have external metallizations on them, and are connected to the electrode layers such that adjacently stacked electrode layers can have different electrical potentials applied to them indirectly via the external metallizations, the stack elements are arranged above one another to form a monolithic total stack, and connected to one another by at least one connecting layer. The following steps are provided: a) provision of the total stack and b) production of a load-relieving crack in the connecting layer. An electrical connector in the form of a wire can be fitted on the relevant external metallization regions.

摘要： The contacting foil (20) for the production of electric conductive connection between two points of a carrier (10), comprises an electrically non-conductive base strip (30) that comprises electric-conductive particles (40) so that the electric conductive particles are brought into contact with each other by electromagnetic radiation (50) and defined local narrowed electric conductive areas are generatable in the contacting foil. The electric conductive particles are foamable through electromagnetic radiation. The contacting foil (20) for the production of electric conductive connection between two points of a carrier (10), comprises an electrically non-conductive base strip (30) that comprises electric-conductive particles (40) so that the electric conductive particles are brought into contact with each other by electromagnetic radiation (50) and defined local narrowed electric conductive areas are generatable in the contacting foil. The electric conductive particles are foamable through electromagnetic radiation by which the electric conductive particles enter in contact within the base strip with each other. The base strip consists of epoxide-material. The electric conductive particle consists of metal and/or partially metallized plastic that is foamable through electromagnetic radiation and/or heat. An independent claim is included for a method for the production of electric conductive connection between two points of a carrier.

摘要： A lead-zirconate-titanate ceramic has texturing, with textured nuclei containing barium-titanate crystallites, wherein the barium-titanate crystallites have a substantially equal crystal characteristic, including form anisotropy, and an orientation in the lead-zirconate-titanate ceramic. A method for the production of a PZT ceramic has the following steps: a) providing the barium-titanate crystallite, b) mixing the barium-titanate crystallite and a starting material of the lead-zirconate-titanate into a ceramic green body such that the barium-titanate crystallites in the green body have an orientation, and c) heat-treating the green body. The heat treatment has calcination and sintering of the piezo-ceramic composition. The barium-titanate crystallites are used in a “template grain growth process” as crystallization nuclei. The piezo-ceramic component is, for example, an ultrasonic transducer or a piezo-ceramic bender actuator. In particular, the piezo-ceramic component is a multilayer piezo actuator, which is used to actuate a fuel valve of an internal combustion engine of a motor vehicle.

摘要： The method involves applying an electrical insulating layer (10) on a surface (20) of a piezo-actuator (5), which runs parallel to its longitudinal or stacking direction (30). A hermetically sealed surface layer is superimposed on the insulating layer, so that the hermetically sealed surface layer covers the insulating layer in a plane. The insulating layer has an organic coating, preferably a polymer or elastomer coating and/or an inorganic coating, preferably of glasses, ceramics, oxides or nitrides. An independent claim is also included for a piezo-actuator with encapsulation, particularly a multilayer actuator.

摘要： The piezo-actuator (1) has a stack (10) with piezo-ceramic layers (111,121), which are arranged one upon the other and electrode layers (112,122) are arranged between the piezo-ceramic layers. A safety layer (13) is arranged in the stack, where the safety layer has a phase transition material. The phase transition material has a phase transition with a phase transition temperature, which lies below a processing temperature of the piezo-actuator. An independent claim is also included for a method for manufacturing of a piezo-actuator.

摘要： In a method for producing a multilayer encapsulation (1) of a piezo actuator (5) such that the piezo actuator (5) is protected towards the outside without having to use an additional enveloping housing-type structure, in order to produce the multilayer encapsulation (1), an electrically insulating elastic layer (10) is first applied to the surface of the piezo actuator (5), whereupon a metallic layer is applied to the electrically insulating elastic layer (10) so as to planarly cover the same.
