Electronic ceramic materials serve as the cornerstone for the advancement of modern electronic information, intelligent manufacturing, and energy technologies. They play a pivotal role in high-end equipment, advanced sensing systems, and novel energy storage solutions. Specifically, ferroelectric piezoelectric ceramics are widely employed in precision actuators, displacement sensors, and intelligent actuators, thanks to their exceptional electromechanical coupling capabilities. On the other hand, antiferroelectric energy storage ceramics exhibit immense potential in pulsed power electronic devices and compact energy storage systems, owing to their high power density, rapid charge-discharge characteristics, and excellent cycle stability. Presently, as related devices progress towards higher precision, lower power consumption, enhanced reliability, and adaptability to complex operational environments, the simultaneous achievement of large electrostrictive strain, minimal energy loss, and long-term stable operation has emerged as a critical focus within the realm of functional electronic ceramics.
