Abstract: The disclosure concerns filled a polymer composite comprising a piezoelectric filler and a polymer resin. The composite may exhibit a piezoelectric coefficient d33 of greater than 30 pC/N when measured according to the Berlincourt Method using a d33 piezometer and a density of less than 5 g/cc according to the Archimedes method.

Abstract: A method of making an aligned piezoelectric composite comprising contacting a thermoplastic material with a plurality of piezoelectric particles to form a thermoplastic material and piezoelectric particles mixture; applying an alternating current electric field across the thermoplastic material and piezoelectric particles mixture to structurally align the piezoelectric particles within the alternating current electric field; heating the thermoplastic material and piezoelectric particles mixture to form a molten polymer composite, while continuing to apply the alternating current electric field; maintaining the alternating current electric field across the molten polymer composite; cooling the molten polymer composite to form a structurally aligned piezoelectric composite, while continuing to apply the alternating current electric field; discontinuing the alternating current electric field; and applying a direct current electric field across the structurally aligned piezoelectric composite to align electric dipoles of the piezoelectric particles within the direct current electric field and to produce the aligned piezoelectric composite.
