Researchers at Tsinghua University in Beijing and Shanghai-based Neuracle Technology have attempted to minimise these risks. Their NEO device sits between the skull and the brain. It presses eight sensors against the patient’s dura mater (the protective outer layer of the brain) and connects these to nearby computers. A central processing hub does the work converting brainwaves into digital commands. Some 36 patients have been trialling the implants. Reportedly with success. That’s bad news for Musk’s brain-implant start-up Neuralink. Its device is yet to receive Food and Drug Administration (FDA) approval for general use, despite beginning human trials in 2024. University of Technology Sydney brain-chip researcher Avinash Singh told the Massachusetts Institute of Technology (MIT) Review that this was likely because the Chinese design is less invasive. Neuralink’s N1 prototype must pierce the cerebral cortex to access brainwaves. “Any kind of brain implant can cause physical damage that may affect how neighbouring brain regions work,” explains Dr Tuffley. Brain chips could improve the lives of more than 3 billion people with neurological conditions, especially those related to movement and speech, according to researchers.

And while infections in the brain are rare, they can cause swelling and further complications if not immediately treated.” The N1 is currently being trialled in nine patients. “I tried writing my name for the first time in 20 years. I’m working on it,” trial participant Audrey Crews said in a post on X. “It’s humbling to know my journey is helping Neuralink refine this technology, which could one day let millions control devices with their minds.” Filed under
