Polymer-derived ceramics (PDCs) have attracted great attention in the applications of high-temperature harsh environments due to its excellent high-temperature semiconductive properties, corrosion/ oxidation resistance, high thermal stability, et al. Therefore, PDCs as sensing material exhibits great potential to be applied in high-temperature harsh environments. This article summarized the research progress on PDCs sensors both domestically and internationally in recent years. The sensing mechanism and related parameters of PDCs sensors were summarized also focusing on temperature sensors, pressure sensors, and strain sensors. At the same time, the performance of relevant ceramic sensors was compared, and the future development of PDCs sensors was discussed finally.Summary and prospects PDCs as sensing material is one of the most promising materials for high-temperature extreme environment applications. This paper summarized the development of PDCs sensors and elaborated the corresponding sensing mechanism. According to the connection type, the properties of existed wired/wirelesses PDCs sensors was compared, results exhibited that the PDCs sensors possess excellent sensitivity, repeatability, stability and fast response, exhibiting competitive performance in high temperature. Meanwhile, PDCs sensor can be prepared on complex surfaces based on the distinctive liquid precursor. Temperature, pressure and strain signals of PDCs sensor can be monitored in-situ and long-distance.However, the development of PDCs sensors is still in infancy stage, and it still exists many obstacles to be overcome. Firstly, it is necessary to eliminate the sensor transmission signal interference through the structural design, and improve the anti-interference ability; Secondly, it is still a challenge to realize the application of PDCs sensors at higher temperature and more complex environments; Finally, the repeatability of wireless PDCs sensors needs to be enhanced by attenuating the interference of wireless transmission signals so that the longer distance transmission can be achieved. In a summary, to realize the practical application of PDCs sensors, some parameters need to be optimized such as structural components, material properties, and production costs.
