Fudan Scientists Weave a ‘Chip’ into Thread — A Step Toward Truly Smart Fabrics

A Fudan University team published a Nature paper describing a 'fiber chip' — polymer fibers that contain multilayer integrated circuits — which could enable fabrics with embedded electronics. The work is a lab-stage milestone with significant promise for wearables, medical devices and brain–machine interfaces, but major engineering, manufacturing and regulatory hurdles remain.
