flag Chinese scientists developed a worm-shaped, magnetically controlled implant that monitors neural activity with high precision and long-term safety in mice.

flag Chinese scientists have created NeuroWorm, a flexible, earthworm-inspired microfiber that moves through body tissues using magnetic control to monitor neural signals and tissue changes. flag About 200 micrometers wide—thinner than two human hairs—it contains 60 nano-scale sensors, 15 times more than traditional devices, enabling precise, long-term, multi-point recordings. flag Tested in mice, the implant remained biocompatible for up to 13 months without adverse reactions. flag Unlike fixed implants, it can navigate the brain or muscles without repeated surgeries, potentially revolutionizing brain-machine interfaces and treatments for neurological disorders like Parkinson’s. flag The study, published in Nature, represents a shift toward mobile, intelligent neural systems. flag Led by Yan Wei of Donghua University and Liu Zhiyuan of the Chinese Academy of Sciences, the team plans to collaborate on advancing clinical use.
