Radiative\nCooling Smart Textiles with Integrated Sensing\nfor Adaptive Thermoregulation

Efficient and adaptive thermoregulation\nof smart wearable\ntechnologies\ncould revolutionize the mitigation of health- and energy-related challenges\nposed by climate change. We developed a woven, thermally adaptive\nsmart textile (TAST) with high solar reflectance and selective infrared\nemittance and transmittance using a scalable coaxial extrusion method\nto continuously manufacture core–sheath fibers. TAST enables\npassive outdoor radiative cooling by 6–10 °C compared\nto normal fabrics while preserving good mechanical strength, breathability,\nand washability. Due to the integration of capacitive sensing, radiative\ncooling, and Joule heating into the woven fibers, TAST can detect\nthe physiological signals of the human body and adapt its thermoregulation\nfunction in response to changes in the ambient temperature and perspiration\nlevel. The superior intelligence and multifunctional performance of\nTAST represent a paradigm shift beyond current personal thermal management\ntechnologies for enhancing human health, wellness, and performance.
