Abstract (en)
[origin: WO2012038223A1] The invention relates to a piezoceramic bending transducer (1) comprising a fixed support (7) at one longitudinal end (13) thereof and having a predetermined deflection direction (15) at the other, free longitudinal end (14) thereof, wherein the bending transducer (1) is formed from a piezoceramic beam (2, 3) and a passive beam (4), which are stacked on one another in the deflection direction (15) and the flexural rigidities of which are designed such that when the bending transducer (1) is deflected, a tension-compression stress transition line (9) settles in the passive beam (4) and the bending stiffness of the passive beam decreases along the tension-compression stress transition line (9) toward the free longitudinal end (14), so that the stress distribution in the piezoceramic beam (2, 3) is homogenous along the tension-compression stress transition line (9) toward the free longitudinal end (14).
