Abstract
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.
