ABSTRACT:
A method of making a polymeric piezoelectric acoustic transducer tape that is thin enough to be stored in roll form and adapted for placement on a lengthy supportive surface is disclosed. A piezoelectric film is heat-formed to provide a plurality of repetitively curved portions therein, conductive electrodes are applied on opposite surfaces of the curved film, a long, narrow layer of flexible, resilient material is adhered to one surface of the curved film and one or more adhesive portions are applied to the surface of the resilient material.
