Nanofiber-based wearable sensor devices with radiative cooling: A review

The application of radiative cooling as a passive thermal management strategy shows considerable promise for improving thermal regulation in wearable sensor devices, thereby significantly enhancing long-term wearing comfort. Electrospinning technology is commonly employed for the development of radiative cooling materials and wearable sensor devices due to its ability to precisely control the mesostructure and functional properties of nanofibers. This paper introduces the principles of preparing radiative cooling membranes and wearable sensor devices by electrospinning. Electrospinning materials used in radiative cooling membranes and wearable sensor devices are then reviewed, and the effect of these materials on improving device performance, enhancing user comfort and expanding applications is analyzed. In the end, this paper summarizes the applications of wearable sensor devices with radiative cooling function in different research fields. Based on the above analysis and discussion, this paper addresses challenges in material mechanical reliability, conductive filler compatibility and preparation cost, and outlines future development directions.
