    摘要： A ceramic multilayer capacitor includes a first capacitor unit, which comprises a first material, and a second capacitor units, which comprises a second material. The first and the second capacitor unit are electrically connected in parallel. At low applied voltages, the first material has a high dielectric value and, at high applied voltages the second material has a high dielectric value.

    摘要： A method for tuning a resonant frequency of a piezoelectric component is disclosed. The piezoelectric component includes a transducer extending in three spatial directions. The resonant frequency depends on an extension in at least one of the spatial directions and/or on a material-dependent elasticity modulus. The transducer includes a layered structure with at least two first electrodes and at least one second electrode, which is disposed between the two first electrodes. In the method, a DC voltage is applied to at least one of the at least two first electrodes and the at least one second electrode, so that a change of the resonant frequency results due to a change to the extension in the one spatial direction and the elasticity modulus. A control voltage with an excitation frequency is applied, the excitation frequency substantially corresponding to the modified resonant frequency. This generates a vibration of the piezoelectric component.

    摘要： A piezoelectric component with a body in which electrically connected transducer elements are realized is disclosed. The transducer elements are separated from each other by an essentially field-free neutral region of the body. A first transducer element has electrically connected first electrodes, and a second transducer element has electrically connected second electrodes. In addition, at least one third electrode, which is arranged in the first and second transducer element is provided. At least three of the first and third electrodes are arranged in an alternating sequence. At least three of the second and third electrodes are arranged in an alternating sequence. The neutral area is perpendicular to the planes in which the electrodes are arranged.
