Abstract

The goal of this research consist in the design, synThesis and optimization of functional piezoelectric ceramics and composites that can be fabricated by Direct Ink Write (DIW) 3D printing technique for the use of sensors and energy storage applications. The synThesis optimization of lead-free ceramics for printing was evaluated by analyzing the impact of raw particle size of BaTiO3. A novel approach to evaluate the effect of bimodal distribution raw particle size of BaTiO3 ceramics is presented and their influence on packing density, piezoelectric coefficient and dielectric relative permittivity. Additionally, multi-material DIW printing was adapted as a novel method to fabricate complete sensors in "one-print" with better bonding. Such method was used for the fabrication of flexible PDMS- BaTiO3 composites with PDMS-MWCNT electrodes.
