Abstract
The invention relates to piezoelectric and pyroelectric transducers whose active element is formed by a polymer film. The invention provides a process for manufacturing a transducer from a flat polymer film which consists in stretching this film over a mold so as to give it a self-supporting form and to electroform this film by means of a corona discharge.
