Abstract

The unique properties of piezopolymers endow them with particular advantages for use in electroacoustic devices such as the self-supporting dome hydrophone shown in the Figure. Thin or especially thick films can be fabricated, and three-dimensional forming of the materials can be accomplished by standard techniques. Further interesting possibilities offered by incorporating a ferroelectric ceramic into a non-electroactive polymer matrix are sketched.
