  • Piezoelectric composite, ink and ink cartridge for 3D printing, bifunctional material comprising the piezoelectric composite, manufacture and uses thereof
    Patent number: 11466169
    Abstract: There is provided a piezoelectric composite comprising a piezoelectric polymer and particles of a filler dispersed in the polymer, wherein the filler is in micro or nanoparticle form and is present in a filler:polymer weight ratio between about 1:99 and about 95:5. There is also provided an ink and ink cartridge for 3D printing of the piezoelectric composite. There is also provided a piezoelectric 3D printed material comprising the piezoelectric composite and a bifunctional material comprising the piezoelectric composite with one or more conductive electrodes adjacent to the piezoelectric composite. Methods of manufacture and uses thereof are also provided, including methods for 3D printing of a piezoelectric 3D printed material via solvent-cast or FDM 3D printing starting from the piezoelectric composite and/or the ink.
    Type: Grant
