Chinese scientists develop flexible fiber chip for smart clothing and brain implants

China has developed a flexible fiber chip that can be woven into fabric, enabling interactive smart clothing and advanced medical implants. This breakthrough, published in Nature, uses a "sushi-roll" technique to create a circuit thinner than a human hair, overcoming the limitations of rigid silicon chips. The durable fiber boasts significant computing power and could revolutionize areas from consumer electronics and virtual reality to high-accuracy brain-computer interfaces.
