Imagine a fiber as thin as a hair can turn into a chip that holds more than 100,000 transistors?per centimeter. A research team at Fudan University in Shanghai has successfully built complex electronic circuits inside thin, flexible fibers. This breakthrough, referred to as a "fiber chip", allows fabrics to process information like a computer while remaining soft enough to be stretched, twisted, and woven into everyday clothing. The research, which challenges the traditional way computer chips are made, was published on Jan 22 in the journal Nature.
