Cover Picture: The fibrous temperature sensor with excellent flexibility, comfort, and ease of integration into fabrics is particularly suitable for body temperature monitoring. However, the detection stability of existing fibrous temperature sensors is greatly affected by external factors. Here, we propose a fibrous temperature sensor based on an optimized scalable ionic liquid immersion process. The proposed sensor exhibited excellent temperature response characteristics, good linearity, a high sensitivity of 2.61%/°C, and can resist disturbances. To demonstrate its application potential, we integrated the sensor into the firefighting suits and designed a multilayer temperature sensing system to monitor both firefighters’ body and ambient temperatures. This system provides timely warnings of overheating in high-temperature and high-humidity environments. Furthermore, we incorporated the fibrous temperature sensors into infant suits, enabling real-time monitoring of body temperature changes and early warning of infant fever.
