Scientists at the University of California, Irvine, have developed a revolutionary fabric inspired by squid skin that allows users to adjust their clothing's temperature. The material, which mimics squid's ability to change light reflection, manipulates infrared radiation emitted by the body to regulate heat. It is washable, breathable, and can be integrated into flexible fabrics, opening possibilities for advanced wearable systems like cold-weather clothing, e-textiles, and energy-harvesting materials.
