Revolutionizing wearable displays with photochromic fibers: Shining as you smile

Achieving uniform and customizable light effects is vital to photochromic fibers in wearable displays. In a recent issue of Light: Science & Applications, an interdisciplinary team led by Lu and Tao developed a mass-produced, wearable, and interactive photochromic fiber that provides uniform, multicolored light control. The applications of the fibers range from everyday wearables to automotive interiors and underwater lighting, providing plenty of new insight into future human-machine integration.
