1. A piezoelectric transducer comprising:

  • an anchorage;

    a cantilever beam of semiconductor material extending from the anchorage in a main direction parallel to a first axis and having a face parallel to a first plane defined by the first axis and by a second axis perpendicular to the first axis;

    a piezoelectric layer on the face of the cantilever beam; and

    a cross-section of the beam perpendicular to the first axis being asymmetrical and configured to cause the beam to deform out of the first plane in response to forces applied to the anchorage and in response to forces parallel to the second axis.
