Over the past two decades, (K_0.5Na_0.5)NbO₃ (KNN)-based lead-free piezoelectric ceramics have made significant progress. However, attaining a high electrostrain with remarkable temperature stability and minimal hysteresis under low electric fields has remained challenge. To address this long-standing issue, we employed collaborative approach that combines defect engineering, phase relaxation engineering. The LKNNS-6BZH ceramic, when sintered at T_sint=1170 ℃, demonstrates an impressive d₃₃* value of 0.276% 1,379 pm·V^-1 under 20 kV·cm^-1, which is comparable to or even surpasses other Pb(Zr,Ti)O₃ ceramics. Importantly, performance ceramic remains stable up 125 lowest observed 9.73% 40 kV·cm^-1. These excellent overall performances are attributed presence dipoles involving  and , coexistence R-O-T multiphase, tuning trade-off between long-range ordering local heterogeneity. This work provides alternative for actuators paradigm designing materials outstanding comprehensive fields.

Abstract Piezoelectricity, a fundamental property of perovskite ferroelectrics, endows the materials at heart electromechanical systems spanning from macro to micro/nano scales. Defect engineering strategies, particularly involving heterovalent trace impurities and derived vacancies, hold great potential for adjusting piezoelectric performance. Despite prevalent use defect modification, comprehensive understanding specific features that positively impact material properties is still lacking, this knowledge gap impedes advancement universally applicable selection design strategy. In work, we select KTa 1− x Nb O 3 single crystals with orthorhombic phase as matrix introduce Fe Mn elements, which are commonly used in “hard” ferroelectrics dopants. We investigate how transition-metal doping modifies perspective intrinsic polarization behaviors. Interestingly, despite both being doped into B-site an acceptor, enhances local structural heterogeneity, greatly bolstering coefficient beyond 1000 pC/N, whereas tends stabilize polarization, leading substantial improvement mechanical quality factor up 700. This work deciphers diverse impacts transition metal on regulating structures modifying properties, providing good paradigm strategically designing ferroelectrics.

Pb(Zr, Ti)O₃-based ceramics are the mainstream materials for commercial multilayer piezoelectric ceramic actuators, but to date, it has not been well solved achieving large strains at low electric fields. Herein, a 0.95Pb(Zr_0.56Ti_0.44)O₃-0.05(Bi_0.5Na_0.5)TiO₃-xBaZrO₃ (PZT-BNT-xBZ) with efficient ferroelectric domain wall motion was designed and realized by reducing lattice distortion changing structure. It is found that introduction of BZ weakens tetragonal phase PZT, contributing reduction in mechanical stress impedes migration walls. Moreover, structures could be modified adjusting content, where short broad striped domains constructed high amplitude characteristics enhance motion. A strain 0.39% accordingly achieved an field as 40 kV/cm sample x = 0.03, accompanied excellent temperature stability over range 30 ^oC 210 ^oC. This study delves into synergistic effects structure on motion, provides effective strategy improve PZT-based ceramic.
