A team of researchers led by material scientist Yoel Fink, have developed a digital fiber that can “sense, memorize, learn, and infer.” Moving beyond previous analogue fibres, it encodes discrete bits of information—the prototype (shirt) can store a “767-kilobit full-colour short movie file and a 0.48 megabyte music file.” It also tracks the body temperature of its wearer, and extrapolates what actitivies they are engaged in with high accuracy, bringing us one step closer to future ‘smart’ clothing that monitors health and vital signs.
