A method for producing an electrical contact is disclosed. In an embodiment the method includes providing a piezoelectric component that includes an electromechanical transducer having two first electrodes and a second electrode arranged between the two first electrodes and spaced from the two first electrodes by a piezoelectric material, the transducer further including a first main side, a second main side opposite from the first main side and a first longitudinal side, and forming a contiguous metallization layer onto a first partial region of the first main side and onto a second partial region along the first longitudinal side, so that the second partial region along the first longitudinal side is at a distance from a side edge facing the second main side and the metallization layer in the second partial region of the first longitudinal side contacts the two first electrodes in an electrically conducting manner.

Method for producing an electrical contact

A piezoelectric component includes an electromechanical transducer with two first electrodes and a second electrode. The second electrode is arranged between the two first electrodes. The transducer also includes a first main side, a second main side, opposite from the first main side, and a first longitudinal side. A first contiguous metallization layer is arranged on a first partial region of the first main side and on a partial region of the first longitudinal side adjacent to the first partial region of the first main side. Here, the partial region of the first longitudinal side is kept at a sufficient distance from a side edge facing the second main side and the partial region electrically contacts the at least two first electrodes.

Piezoelectric component and method for producing an electrical contact

An electrical multilayer component has a stack of dielectric layers and electrode layers arranged one above another. An electrically insulating stiffening element is arranged at a distance from at least one electrode layer on the same dielectric layer as the electrode layer. The stiffening element preferably has an increased flexural strength with respect to dielectric material surrounding it.
