  • Flexible polyoxymethylene-based piezoelectric composites
    Patent number: 11444236
    Abstract: 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 BaTiO3 and KNN. The polymer composite thin film exhibits piezoelectric characteristics and may be used in electronic devices in piezoelectric actuators and piezoelectric sensors.

  • NOVEL PIEZOELECTRIC COMPOSITION AND FILMS WITH HIGH D33 VALUES AND IMPROVED ADHESION AND FLEXIBILITY
    Publication number: 20220254986
    Abstract: 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.
