    摘要: The invention relates to a high-lifting capacity piezoelectric actuator (1) comprising an piezoelectric layer (10) and a second layer (20) whose material gradient is directed to the thickness. An electric field produces different extension degrees in said piezoelectric layer (10) and in the second layer (30), thereby increasing the lifting capacity of the piezoelectric actuator (1) in combination with an impressed mechanical prestressing. The inventive piezoelectric actuator is used at a low voltage, for example, for bio and medical engineering (micropumps, microvalves), in industrial electronic engineering (pneumatic valves) and for microactuators and micromotors.

    摘要: Piezoelectrical bending converter with at least one monolithic layered composite, includes a piezoelectric-active ceramic layer with a lateral dimension change which may be generated by application of an electrical field and at least one further piezoelectric-active ceramic layer with a further lateral dimension change, different from the lateral dimension change. An electrode layer is arranged between the ceramic layers, for generation of the electric fields. The layered composite preferably comprises several piezoelectric-active layers and electrode layers arranged between the above. The shift is thus obtained as a gradient of the dimension changes in the direction of the stack of the layered composite. The dimension changes for the ceramic layers and the gradient may be adjusted by the generation of the electrical fields. In order to achieve a shift it is necessary not to have a piezoelectric-inactive layer.

    摘要: An additional contacting (30) for a piezoelectric component (10) is formed as a multilayer structure, wherein the piezoelectric component (10) is formed by a stack (16) of alternatingly arranged piezoelectric ceramic layers (11) and electrode layers (12, 13). The additional contacting (30) has a series of connecting elements (31) for connecting a metallization (15) of the electric component (10) to an electrical connecting element (19). In order to minimize mechanical loads during dynamic operation of the piezoelectric component (10), the additional contacting (30) is configured as an individual, structured component (32), especially in the form of a structured foil. Said structured foil (32) advantageously has a current conduction path (33) which is common to the connecting elements (31) and a contacting zone formed in the area of static base plate (17), wherein the additional contacting (30) is connected to the electrical connecting element in the area of said contacting zone.

    摘要: An apparatus couples mechanical energy in the form of wide-range mechanical vibrations to a piezo sensor, especially a multi-layer piezo sensor, for converting the mechanical energy into electric energy. The apparatus has a housing onto which the mechanical energy acts in the form of the vibrations, and a vibrating mass provided within the housing. The vibrating mass is clamped with at least two piezo sensor units in the housing. An apparatus thus adapts a piezo sensor energy converter for a wide range of frequencies and amplitudes of mechanical vibrations.

    摘要: A piezoelectric component with at least one fully active piezoelement has electrode layers and interposed piezoelectric layers guided to a lateral edge of the piezoelement and contacted there. An insulating layer applied for electric contacting has an electric through-plating. An electrically conductive gas-phase deposition layer is applied directly to the electrode layer guided up to the lateral surface of the piezoelement by way of deposition from the gas phase in order to improve electric contacting. An external electrode is applied to the gas-phase deposition layer. In the case of several superposed stacked piezoelements (piezoactuator in multi-layer design), the external electrode functions as a collector electrode which connects the electrode layers to each other. The structure enables secure contacting of the electrode layers. A fully active piezoceramic multi-layer actuator with the described contacting may be used in automobile technology for activating fuel-injection valves.

    摘要: The embodiments relate to a piezoelectric component including at least one fully active piezoelectric element comprising electrode layers and piezoelectric layers arranged therebetween. The electrode layers are conveyed to a lateral edge of the piezoelectric element and contacted there. The external electrode is attached in a structured fashion for electrical contacting and/or a structured external electrode is made available: The external electrode essentially includes two components, namely the contacting field and the contacting path. In the event of several piezoelectric elements (piezoelectric actuator in multilayer structure) stacked one above the other, the contacting path functions as a collector electrode, which connects the contacting fields of the piezoelectric elements to one another. The insulation path exists for the electrical insulation of the contacting path from electrode layers which are not to be contacted. A reliable contacting of the electrode layers is possible with the structure according to the invention. A fully active, piezoceramic multilayer actuator with the described contacting is used in automotive engineering for activating fuel injection valves.
