传统上，有效的机械振动能量收集基于（Pb，Zr）TiO 3（PZT）陶瓷、聚偏二氟乙烯（PVDF）聚合物或PVDF/PZT或其它压电复合材料，并且它们的工作温度通常限于室温（R-T）或低于150摄氏度。在此，报道了具有约450 ℃的高居里温度点的铋钪钛酸铅（BiScO 3-PbTiO 3，缩写为BSPT）陶瓷及其用于高温（H-T）振动能量收集的应用。实验结果表明，它具有优良的H-T压电性，在R-T至250 ℃的较宽温度范围内有效地将机械振动能转化为电能。研究表明，BSPT压电能量采集器作为高温环境下无线传感器网络系统的自供电电源具有潜在的应用前景。
Conventionally, effective mechanical vibration energy harvesting is based on (Pb,Zr)TiO3 (PZT) ceramics, poly(vinylidene fluoride) (PVDF) polymers or PVDF/PZT or other piezoelectric composite materials, and their working temperature is normally limited to room temperature (R-T) or below 150 degrees C. Here, bismuth scandium lead titanate (BiScO3-PbTiO3, abbreviated as BSPT) ceramic is reported which has a high Curie temperature point around 450 degrees C and its application for high-temperature (H-T) vibration energy harvesting. Experimental results show that it exhibits an excellent H-T piezoelectricity, converting mechanical vibration energy into electric power effectively in a wide temperature range from R-T till 250 degrees C. This research shows the BSPT piezoelectric energy harvester having the potential application for self-power source of wireless sensor network system in high temperature circumstance.
