ABSTRACT:
The invention relates to piezoelectric polymer films.
The invention relates to a production process consisting of stretching a polymer material blank by rolling under an electrical field between two oppositely rotating rollers.
The invention is more particularly applicable to the production of electromechanical transducers, whose active elements are constituted by piezoelectric polymer films provided with electrodes.
