ABSTRACT:
A piezoelectric polymer hydrophone including a single flexible sheet of a ezoelectric polymer having a plurality of electrode strips on the top and bottom of the sheet. The electrode strips at the top are staggered by one half the width of a strip relative to the corresponding strips at the bottom of the sheet. The polymer sheet can be rolled into a helix without losing its acoustic sensitivity.
