Perspective on the Development of Lead‐free Piezoceramics

A large body of work has been reported in the last 5 years on the development of lead‐free piezoceramics in the quest to replace lead–zirconate–titanate (PZT) as the main material for electromechanical devices such as actuators, sensors, and transducers. In specific but narrow application ranges the new materials appear adequate, but are not yet suited to replace PZT on a broader basis. In this paper, general guidelines for the development of...
