工业界和科学界已经表达了对高温下压力、声学和振动传感能力的真实的需求。本文比较了各种商业方法和材料的声转换，确定其优点和局限性。技术和设备包括简单的压电传感器、加速度计、应变仪、接近传感器、光纤和缓冲棒。工作温度超过650摄氏度的传感器很容易从商业来源获得。在所研究的机制中，压电方法提供了几个优点，包括设计成本和简单性。因此，这篇评论的大部分集中在压电材料上，既有那些已经商业化的，也有那些目前正在开发中的。新材料包括钙钛矿层状结构铁电陶瓷，它具有已知的最高居里温度，和薄膜AlN，据报道，在1150 ℃下具有压电活性
The industrial and scientific communities have expressed a real need for the capability of pressure, acoustic, and vibration sensing at elevated temperatures. This review compares the various commercial methods and materials for acoustic transduction, identifying their advantages and limitations. Techniques and devices include simple piezoelectric sensors, accelerometers, strain gauges, proximity sensors, fiber optics and buffer rods. Sensors with operating temperatures in excess of 650-degrees-C are readily available from commercial sources. Of the mechanisms investigated, the piezoelectric approach offers several advantages, including design cost and simplicity. Therefore, the bulk of this review concentrates on piezoelectric materials, both those that are already available commercially, and those that are presently under development. The new materials include perovskite layer structure ferroelectric ceramics, which possess the highest known Curie temperatures, and thin film AlN, which has been reported to be piezoactive at 1150-degrees-C
