ABSTRACT:
A flexible, composite, acoustical energy transducer made from ferroelectric, piezoelectric, and/or electrostrictive materials in combination with a polymer, such as silicone or polyvinylidene fluoride (PVF.sub.2), preferably having electroelastic properties. The materials are formed into platelets or wafers which have electrodes on their facial surfaces and are arranged within the polymer with each wafer in the same x-y plane such that their polarizations are in the same direction and perpendicular to the x-y plane. The wafers are aligned in directed rows, spaced from each other and are totally encased within the polymer. Thin conductive sheet or foil electrodes are secured to the upper and lower faces of the polymer and a conductive material between each wafer and the foil electrically connects the wafers to the foil electrodes. To protect the electrodes and prevent electrical shorting, a rubber coating or any other suitable insulator may be applied to the outside of the electrodes. The polymer is flexible and therefore the transducer can be formed into most any desired shape or placed on a flat or curved surface.
