As aeroengine thrust-to-weight ratios continue to improve, the operating temperature of their hot-end components has risen steadily, placing stricter demands on the performance of temperature sensors. Among potential solutions, negative temperature coefficient (NTC) thermistors—known for their low cost, small size, and fast response—are emerging as a promising candidate for next-generation advanced temperature sensors. However, extreme high-temperature environments pose significant challenges to the structural and electrical stability of thermosensitive ceramics, the core component of such thermistors.
