High-temperature pressure sensors can be widely used in industries with high-temperature working conditions, such as aerospace, automotive, petroleum industry and fire protection. Pressure sensors with excellent sensing performance and high-temperature tolerance will have broad application prospects in harsh environments. This review summarizes the research progress of high-temperature pressure sensors from aspects ranging from materials and working mechanisms to temperature compensation methods. Finally, challenges and trends in the field are briefly discussed. It is expected to benefit the scientific research community and promote further research and applications of high-temperature sensors.

A textile pressure sensor with high-temperature resistance, which can work at temperatures up to 300 °C and withstand a high temperature of 900 °C in N ₂ , was fabricated by printing multi-wall carbon nanotubes (MWCNTs) electrodes on quartz fabrics.

Flexible conductive films based on light-to-heat conversion are promising for the next-generation electronic devices. A flexible waterborne polyurethane composite film (PU/MA) with excellent photothermal conversion performance was obtained by combination of PU and silver nanoparticle decorated MXene (MX/Ag). The silver nanoparticles (AgNPs) uniformly decorated on the MXene surface by γ-ray irradiation induced reduction. Because of the synergistic effect of MXene with outstanding light-to-heat conversion efficiency and the AgNPs with plasmonic effect, the surface temperature of the PU/MA-II (0.4%) composite with lower MXene content increased from room temperature to 60.7 °C at 5 min under 85 mW cm⁻² light irradiation. Besides, the tensile strength of PU/MA-II (0.4%) increased from 20.9 MPa (pure PU) to 27.5 MPa. The flexible PU/MA composite film shows great potential in the field of thermal management of flexible wearable electronic devices.

A pressing concern regarding wearable devices is the waste disposal challenges posed by their widespread use. This paper proposes an eco-friendly pressure sensor with a piezoresistive/capacitive dual-response mechanism.
