ABSTRACT:
Piezoelectric and pyroelectric transducers whose active element is formed by a polymer film. The transducer is manufactured from a flat polymer film by stretching this film over a mold so as to give it a self-supporting form and electroforming the stretched film by means of a corona discharge so as to induce in the polymer film a macromolecular chain translation between reversed and non-reversed neighboring chains.
