压电材料的研究新进展

New advances in piezoelectric materials

压电材料作为机电转换的功能材料,在高新技术领域扮演着重要的角色。锆钛酸铅压电陶瓷凭借其优良的性能,自投入使用以来成为最广泛使用的压电材料。近年来,探索和发展潜在的替代新型材料备受重视。本文就近些年来国内外压电材料技术研究进展中呈现的无铅化、高性能化、薄膜化的新趋势进行了综述,并对今后的研究提出一些发展性的建议。

Piezoelectric materials play an important role in higlh technology application fields as functional materials using their electromechanical transduction ability. Lead zirconate titanate （PZT） piezoceramics has become the most widely used piezoelectric materials with excelLlent performance since it was first put into practical usage around 1950. Recently, scientific interest has been focused on exploration and development of novel materials as potential candidate for future devices requirement. The lead-free, high performance piezoelectric materials and thin film piezoelectric materials are developed rapidly. The new advances in this field are reviewed. Some suggestions for future research are also proposed in order to promote the piezoelectric materials development to meet the new challenges.
