The design of lead-free ceramics for piezoelectric energy harvesting applications has become a hot topic. Among these materials, BaCaZrTiO (BCZT) and BaTiSnO (BTSn) are considered as potential candidates due to their enhanced piezoelectric properties. Here, the structural, electrical, piezoelectric and piezoelectric energy harvesting properties of the (1 - )BaCaZrTiO-BaTiSnO (BTSn, = 0.2, 0.4 and 0.6) system are investigated. A systematic study of the structural properties of the BTSn samples was carried out using X-ray diffraction, Raman spectroscopy, and dielectric measurements. The addition of BTSn allows a successive phase transition, which broadens the application temperature range. The enhanced piezoelectric energy harvesting properties were found in the 0.2BTSn ceramic, where the large-signal and small-signal piezoelectric coefficients, piezoelectric voltage and the piezoelectric figure of merit reached 245 pm V, 228 pC N, 16.2 mV m N and 3.7 pm N, respectively. Consequently, the combination of BCZT and BTSn could provide suitable lead-free materials with enhanced piezoelectric energy harvesting performances.
用于压电能量收集应用的无铅陶瓷设计已成为一个热门话题。在这些材料中，BaCaZrTiO（BCZT）和BaTiSnO（BTSn）因其增强的压电性能而被视为潜在候选材料。在此，研究了(1 - )BaCaZrTiO-BaTiSnO（BTSn， = 0.2、0.4和0.6）体系的结构、电学、压电和压电能量收集性能。使用X射线衍射、拉曼光谱和介电测量对BTSn样品的结构性能进行了系统研究。BTSn的加入允许连续的相变，从而拓宽了应用温度范围。在0.2BTSn陶瓷中发现了增强的压电能量收集性能，其中大信号和小信号压电系数、压电电压和压电优值分别达到245 pm V、228 pC N、16.2 mV m N和3.7 pm N。因此，BCZT和BTSn的组合可以提供具有增强压电能量收集性能的合适无铅材料。
