Nature Communications, Published online: 25 April 2026; doi:10.1038/s41467-026-72335-6 The authors integrate morphotropic phase boundary engineering with high-entropy design in a quinary perovskite ceramic, which yields a piezoelectric coefficient of 580 pC/N and exceptional thermal stability, with performance retained up to 285 °C.
