Scientists from Fudan University have developed a soft "fiber chip" — a flexible integrated circuit detailed in Nature. Made inside elastic polymer fibers with a multi-layer helical design, the chip maintains full processing ability while stretched, knotted, or deformed. This overcomes rigid chips’ limits in wearable tech and enables progress in brain-computer interfaces, smart textiles, and immersive VR systems. (Photo/China Youth Daily)
