High‐Performance Strain of Lead‐Free Relaxor‐Ferroelectric Piezoceramics by the Morphotropic Phase Boundary Modification (Adv. Funct. Mater. 32/2022)

Lead-Free Piezoceramics In article number 2202307, Linglong Li, Dong Wang, and Xiaojie Lou, and co-workers report a computationally aided composition design for discovering high-performance lead-free perovskite piezomaterials. The obtained bismuth sodium titanate-based relaxor-ferroelectric ceramic demonstrates low-hysteresis large strains over a wide range of temperatures, which holds great promise for practical applications of actuator devices operating at room to high temperatures.
