Ultrahigh piezoelectricity and temperature stability in piezoceramics by synergistic design.

ABSTRACT: Piezoceramics with both high piezoelectric properties and broad temperature usage range are highly in demand for sensor and actuator applications. Unfortunately, the trade-off relationship between two properties poses a significant challenge that remains unresolved. Herein, through combined phase boundary engineering and process engineering, we report the simultaneous achievements of substantially enhanced piezoelectric coefficient d₃₃ (from 784 pC/N to 855 pC/N) and piezoelectric strain d₃₃* (from 620 pm/V to 860 pm/V), and ultrahigh temperature stability (i.e., d₃₃ and d₃₃* change less than 7.3% and 4.6% over 25-175 °C, respectively) in Pb_0.92Ba_0.08[Zr_0.50+xTi_0.48-x(Nb_0.5Sb_0.5)
