    • The invention relates to a piezoelectrical bending converter (1) with at least one monolithic layered composite (2, 21), comprising a piezoelectric-active ceramic layer (31) with a lateral dimension change (311) which may be generated by application of an electrical field (312) and at least one further piezoelectric-active ceramic layer (32) with a further lateral dimension change (321), different from the lateral dimension change (311). The bending converter is characterised in that an electrode layer (411) 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 (22) of the layered composite. The dimension changes for the ceramic layers and thus the gradient may be adjusted by means of the generation of the electrical fields. In order to achieve a shift it is necessary not to have a piezoelectric-inactive layer. The layered composite is preferably a circular disc bending body (21), with a circular base body. A large shift ratio is obtained by means of arranging several circular disc bending bodies in a stack.
    • 本发明涉及一种具有至少一个单片层压板(2,21),包括一个压电活性陶瓷层(31),其具有通过电场(312)可以产生的横向尺寸变化率(311)和至少一个其它压电活性陶瓷层的压电弯曲换能器(1) 通过横向尺寸变化率(311)的各种其它横向尺寸改变(321)的另一电场(322)来生成(32)与。 其特征在于所述弯曲换能器的特征在于:电极层(411)被布置为生成在陶瓷层之间的电场。 优选地,多个压电活性陶瓷层和电极层的所述复合层设置在其间。 行程由在层复合材料的层叠方向(22)的尺寸变化的梯度来实现的。 陶瓷层和梯度的尺寸变化可以通过电场的产生来设置。 为了得到弯曲换能器的行程不要求压电非活性层。 复合层最好是圆盘弯曲机(21)具有圆形底部区域。 对于一个大的行程乘法几个圆盘弯曲机被叠加,以形成叠层。

    • The invention relates, inter alia, to an additional contacting (30) for a piezoelectric component (10) in the form of 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 (19) in the area of said contacting zone (34).
