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.

摘要： The invention relates to a piezoceramic composition with the general empirical formula Pb1-aREbZrxTiyTRzO3, in which RE represents a rare-earth element, selected from a group comprising europium, gadolinium, lanthanum, neodymium, praseodymium, promethium and/or samarium, with a rare-earth element fraction b, TR represents at least one transition metal, selected from the group comprising chromium, iron and/or manganese, with a transition metal valency W TR and a transition metal fraction z and whereby the following interrelation is valid: z>b/(4−W TR ). Homogenous PZT crystals with a maximum particle size are obtained even at low sintering temperatures by a non-stoichiometric dosing ratio of transition metal dosage to rare-earth element dosage. By varying the dosages, the piezoelectric characteristics of a PZT ceramic with said composition can be modified from those of a classic soft PZT to those of a classic hard PZT. The piezoceramic body is for example a monolithic, multi-layer piezoactuator, which can be used for multiple injections in the engine of a motor vehicle, as a result of a high d33 coefficient and low internal dissipation in the high-level signal range.

摘要： A ceramic element includes at least one substantially homogeneous ceramic layer which is provided with a plurality of superimposed partial ceramic layers. The ceramic element can be produced by stacking partial homogeneous ceramic layers on top of each other in the form of ceramic green films, removing the binding agent, and sintering. The ceramic element can be compacted at a lower sintering temperature than conventional block sinters. Moreover, the ceramic layer of the ceramic element is provided with a low number of pores, enclosures, foreign phases, and other flaws and is highly homogeneous. The ceramic element particularly represents a piezoelectric bending transducer or a piezoelectric transformer. Advantageously, the bending transducer or transformer has electrodes so as to be electrically triggered, the electrodes being buried underneath another ceramic layer. The additional ceramic layer and/or the electrode layer are used as a diffusion barrier.

摘要： A piezo actuator (1) is disclosed that has a contact lug (20, 21) for the electrical contacting of an electrode (14, 15) of an actuator member (11). Due to an expansion and contraction of the actuator member, a mechanical stress occurs in the contact lug that is minimized in that the contact lug has a device for adapting the expanse to a dimension of the expansion and contraction. The device is, for example, a deformation material in the form of a wire weave. The piezo actuator is utilized for the drive of an injection valve in an internal combustion engine.
