The fibers could feasibly "be woven into light-emitting clothes for the creation of smart fabrics" or used for biomedical applications, according to lead scientist Zhitao Zhang from Shanghai's Fudan University. However, there are a few hurdles to clear. The fibers are too short to be woven into clothing and, like your old Christmas tree lights, are still too unstable. On the other hand, they require less power than LEDs and are transparent and conductive -- meaning they have potential to be used for human- or solar-powered wearables. We could also see them in future invisibility cloaks if combined with tiny cameras. For now, it's just a rough prototype, but display tech often goes from concept to reality a lot faster than other scientific pipe dreams.
