Abstract

A piezoelectric flexural transducer having an elongated support body (2), that on at least one longitudinal side is provided with a piezoelectric multi-layer body (6). In the interior of the support body (2) and/or between the support body (2) and the piezoelectric multi-layer body (6) and/or between neighboring piezoelectric material layers of the piezoelectric multi-layer body (6) at least one component (24 and 32) of an electronic (23) and/or sensor (33) system is accommodated employed for the operation of the piezoelectric flexural transducer.
