摘　　要：近年来,随着汽车、石油、核电和航空航天等高温领域的发展,应用于极端环境中的无损检测、可持续自供电设备用宽温域压电材料成为研究热点。然而,具有优异压电性和高温稳定性的宽温域压电材料,由于质脆、硬度大,致使所制器件无法兼具柔性及高温稳定性而在高温精密化作业、可穿戴健康检测等应用中受到极大限制。因此基于宽温域压电材料的柔性化设计,以实现耐高温柔性压电装置的制备并最终大幅拓宽压电装置的高温工作潜力,成为目前压电器件的重要发展方向。本文首先针对300℃以下环境中应用的压电材料(锆钛酸铅、钛酸钡和碱金属铌酸盐)和500~1000℃环境中应用的Ⅲ族氮化物的研究进展进行了介绍,然后分析基于这些材料的柔性化设计技术及柔性化设计过程中所用衬底或复合基体的种类对最终器件高温稳定性的影响。With the development of high temperature fields,such as automotive,petroleum,nuclear power and aerospace,piezoelectric materials with wide temperature range,as the core component of nondestructive testing and sustainable self-powered equipment used in these extreme environments,have become the hotspot of research in recent years.However,even the piezoelectric materials with wide temperature range owning excellent piezoelectricity and high temperature stability,the devices made of them could not have both flexibility and high-temperature resistance due to the embrittlement and hardness,resulting in the limitation in the application of high temperature precision operation and wearable health testing.Therefore,the flexible design of piezoelectric materials with wide temperature range,which can realize the preparation of high-temperature resistant,soft piezoelectric device and ultimately broaden the high temperature potential of device,become an important development direction for piezoelectric field.The research progress of piezoelectric materials with wide temperature range was introduced first in this paper,which includes materials(PZT,BT,KNN)used in the environment below 300℃andⅢ-N material used in 500-1000℃.Then the flexible design technology was collected based on these materials,including direct-growth,growth-transfer and nano-composite.In the meantime,the influence of types of substrates or composite matrix on the high-temperature stability of final device was also analyzed.
