This work is aimed at fabricating nanocomposites based on ZnO nanostructures and nanocellulose dispersed in a UV-cured acrylic matrix (EB), as functional coatings for self-powered applications. Aluminum nitride (AlN) film integration on the beam and proof mass insertion at the tip were also considered in order to increase the piezoelectric response. The root mean square (RMS) open circuit output voltage of all devices was recorded at different applied accelerations. The incorporation of ZnO nanostructures into the acrylic matrix favored an ordered structural arrangement of the deposited AlN layer, hence improving the piezoelectric response of the resulting nanocomposites, reaching 4.5 mV for the AlN-coated system containing ZnO nanoflowers.

Abstract

This work is aimed at fabricating nanocomposites based on ZnO nanostructures and nanocellulose dispersed in a UV-cured acrylic matrix (EB), as functional coatings for self-powered applications. Aluminum nitride (AlN) film integration on the beam and proof mass insertion at the tip were also considered in order to increase the piezoelectric response. The root mean square (RMS) open circuit output voltage of all devices was recorded at different applied accelerations. The incorporation of ZnO nanostructures into the acrylic matrix favored an ordered structural arrangement of the deposited AlN layer, hence improving the piezoelectric response of the resulting nanocomposites, reaching 4.5 mV for the AlN-coated system containing ZnO nanoflowers.
