本文综述了压电传感器和传感器材料技术的现状和历史发展。首先讨论了压电和铁电活性的基础，然后概述了最常用的压电陶瓷：锆钛酸铅（PZT）。讨论了压电晶体和附加压电陶瓷的性质和应用，然后描述了由大块陶瓷制备的几种传感器结构。本文还对基于组成相连通性的压电陶瓷-聚合物复合传感器进行了广泛的综述和比较。我们用最近的压电陶瓷-金属复合传感器的例子来结束我们对传感器结构的讨论，并展望压电传感器领域的未来发展。
This paper reviews the current trends and historical development of piezoelectric sensors and sensor materials technology. It begins with a discussion of the bases of piezo- and ferroelectric activity, followed by an overview of the most commonly used piezoelectric ceramic: lead zirconate titanate (PZT). A discussion of the properties and applications of piezoelectric crystals and additional piezoelectric ceramics is followed by a description of several sensor configurations prepared from bulk ceramics. An extensive review and comparison of piezoelectric ceramic-polymer composite sensors based on the connectivity of the constituent phases is also presented. We conclude our discussion of sensor configurations with recent examples of piezoelectric ceramic-metal composite sensors, and expected future developments in the area of piezoelectric sensors.
