Abstract

The disclosure provides in one embodiment a method of fabricating a lead zirconate titanate (PZT) nanoparticle ink based piezoelectric sensor. The method has a step of formulating a lead zirconate titanate (PZT) nanoparticle ink. The method further has a step of depositing the PZT nanoparticle ink onto a substrate via an ink deposition process to form a PZT nanoparticle ink based piezoelectric sensor.
