ABSTRACT:
A piezoelectric transducer having at least one active element consisting of a film of polymer material is disclosed. Electrodes are formed on the two principal faces of the film after polarization of the film. The film is endowed with piezoelectric properties under the sole action of an electric field oriented along the normal to its principal faces and without any need for preliminary stretching. The anisotropy induced as a result of this orientation is solely electrical.
