PIEZOELECTRIC POLYMER TRANSDUCERS

摘要

A piezoelectric transducer of piezoelectric plastics material comprises a body (10) and activated transducer film (11) formed integrally. Electrodes (12) are formed on opposite sides of the film, and a backing material (14) supports the film (11) on one side. The transducer may be formed by moulding, applying the electrodes and activating the film by means of a Corona discharge.
