A piezoelectric flexural transducer having an elongated support body (2) which on at least one longitudinal side is provided with a piezoelectric unit (5). The piezoelectric unit (5) has one or more piezoelectric material layers (12) and electrodes (13a and 13b) associated with same. Furthermore, the piezoelectric unit (5) includes an electrically insulating coating surrounding the body (8) right round it, the section (26) of the coatings lying between the piezoelectric body (8) and the support body (2) being provided with one or more electrically conductive vias (27a and 27b). The latter provide the necessary electrical connection between the electrodes (13a and 13b) and the support body (2).
A piezoelectric flexural transducer comprising an elongated support body which on at least one longitudinal side is fitted with a piezoelectric unit, which has a piezoelectric body with one or more piezoelectric material layers and electrodes associated with same, characterized in that the piezoelectric unit comprises an electrically insulating coating surrounding and encasing the piezoelectric body, such coating being provided with one or more vias for making electric contact with the electrodes.
