In a paper published in the journal Science on April 19, 2019, multiple researchers affiliated with the Materials Research Institute and labs in China, Australia and the United States report a piezoelectric material with the highest piezoelectric charge to date. Piezoelectrics are widely used as sensors, transducers, in electromechanical systems and in ultrasound. In this case, the relaxor perovskite oxide single crystal is doped with the rare-earth element samarium. MRI-affiliated authors include lead author Fei Li, Long-Qing Chen, Thomas Shrout and Shujun Zhang.
