Disclosed are piezoelectric compositions and films with high D33 values and improved surface smoothness, scratch resistance and/or adhesion. The compositions and films can have a combination of benefits over the prior art compositions and films by having two different polymers (i.e., EVA and PVDF-TrFE-CFE) blended into a polymer matrix, to which is added piezoelectric additives like PZT, BaTiO3, etc. at greater than 70-90 wt. % loading. Devices utilizing the compositions and films are also disclosed. Such devices can include sensors, transducers, actuators, or wearable devices.

Piezoelectric composition and films with high D33 values and improved adhesion and flexibility

A polymer composite thin film exhibiting piezoelectric properties may include a polymer matrix with base material of Polyoxymethylene (POM) and a piezoelectric additive of greater than approximately five (5) percent by weight of the polymer composite thin film. The piezoelectric additives may include BaTiOand KNN. The polymer composite thin film exhibits piezoelectric characteristics and may be used in electronic devices in piezoelectric actuators and piezoelectric sensors.

Flexible polyoxymethylene-based piezoelectric composites

The disclosure concerns healable polycarbonate resins comprising at least about 5 mol % of disulfide units, articles comprising the healable polycarbonate resin, and methods of activating the healable polycarbonate resin by exposing the healable polycarbonate resin to heat or radiation.
