MIT Engineers Showcases A Programmable Digital Fiber Featuring Memory Unit, Sensors & AI The digital fiber comprises memory, temperature sensors, and a taught neural network algorithm for detecting physical exercise. Researchers at MIT have developed the world’s first programmable digital fiber, which can sense, store, analyses, and infer activity after being stitched into a garment. Digital fibers, according to Yoel Fink, a professor of material sciences and electrical engineering, a principal investigator at the Research Laboratory of Electronics, and the study’s senior author, expand the possibilities for fabrics to uncover the context of regularities in the human body that can be used for physical fitness tracking, medical inferential, and initial disease detection.
