Lead Free Piezoelectric Materials

Journal of Electroceramics, 2004
Lead oxide based ferroelectrics, represented by lead zirconate titanate (Pb(Zr, Ti)O3) or PZT) are the most widely used materials for piezoelectric actuators, sensors and transducers due to their excellent piezoelectric properties. Considering lead toxicity, there is interest in developing piezoelectric materials that are biocompatible and ...

Lead-free piezoelectric-metal-cavity (PMC) actuators

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2008
A piezoelectric piezoelectric-metal-cavity (PMC) actuator was reported previously that can exhibit a large flexural displacement. In this paper, a lead-free piezoelectric ceramic was used as a driving element of the PMC actuator. Bi(0.5)(Na(0.725)K(0.175)Li(0.1))(0.5)TiO3 (abbreviated as BNKLT) is a soft-type piezoelectric ceramic with good ...

Ultra-High Piezoelectric Performance by Rational Tuning of Heterovalent-Ion Doping in Lead-Free Piezoelectric Ceramics

Nano Energy, 2022
The vision of “lead-free” instead of “lead” is growing as people pay more attention to environmental problems, especially since performance improvement of lead-free piezoelectric materials is imminent.

Lead-free multilayer piezoelectric transformer

Review of Scientific Instruments, 2007
In this article, a multilayer piezoelectric transformer based on lead-free Mn-doped 0.94(Bi1∕2Na1∕2)TiO3–0.06BaTiO3 ceramics is presented. This piezoelectric transformer, with a multilayered construction in the thickness direction, is 8.3mm long, 8.3mm wide, and 2.3mm thick. It operates in the second thickness extensional vibration mode.

Lead-free piezoelectric ceramics vs. PZT?

Journal of Electroceramics, 2006
Investigations in the development of lead-free piezoelectric ceramics have recently claimed properties comparable to that of PZT-based materials. In this work, the dielectric and piezoelectric properties of the various systems were contrasted in relation to their respective Curie temperatures.
