Recent Progress on BaTiO3-Based Piezoelectric Ceramics for Actuator Applications

Actuators, 2017
Due to issues with Pb toxicity, there is an urgent need for high performance Pb-free alternatives to Pb-based piezoelectric ceramics. Although pure BaTiO3 material exhibits fairly low piezoelectric coefficients, further designing of such a material ...
