Large piezoelectricity and high depolarization temperature in BiScO₃–BiYbO₃–PbTiO₃ ceramics for energy harvesting at elevated temperatures

Abstract

Large high-temperature d33 and high Td are simultaneously realized in new BS–BY–PT ceramics for piezoelectric energy harvesting.

Piezoelectric Properties and Thermal Stability of Pb(Yb1/2Nb1/2)O3-BiScO3-PbTiO3 Ternary Ceramics

“…Compared with the unmodified BS-PT binary system, P r is greatly improved, which proves that the introduction of PYN optimizes the ferroelectric properties of BS-PT. The electric field-induced strain of the piezoelectric material is an important parameter in the design of the actuator, which comes from the intrinsic contribution provided by the inverse piezoelectric effect and the extrinsic contribution caused by the domain wall motion [37]. Figure 7 presents the electric field-induced strain curve of the PYN-BS-xPT ceramic.…”
