High-temperature and high-pressure sensor is a pressure-sensitive device that utilizes high-strength metal as the base material and employs advanced processing techniques to deposit a glass-ceramic hybrid material on the surface of the substrate using ultra-high-temperature sintering. This technology involves the study of interface mechanics, thermodynamics, molecular dynamics, and electronics, which makes it a multidisciplinary and cutting-edge technology in the field of high-tech sensing. The high-temperature and high-pressure sensor finds extensive applications in detecting pressure from various media in different environmental conditions.
