China races to develop brain-computer interfaces that can be inserted in 10 minutes

Chinese start-ups and researchers are racing to bring Brain-Computer Interfaces (BCIs) to market that can be implanted in just a few minutes, as Beijing pushes to nurture home-grown players in the sector to compete with Elon Musk’s Neuralink.The Chinese devices – which enable patients to control digital technology using their thoughts alone – can be inserted via a vein like a stent, unlike conventional BCIs that require patients to undergo brain surgery.StairMed Technology – one of the start-ups involved – “is developing a more minimally invasive way of delivering the device, entering through blood vessels in the neck and guiding it through the vascular system directly into the brain,” said Zhao Zhengtuo, the company’s co-founder, at the Global Health Summit in Hong Kong on Saturday.The Shanghai-based firm has raised more than 1.1 billion yuan (US$163 million) in funding over the past year to push forward with its research, with investors including the Chinese tech giants Tencent Holdings and Alibaba Group Holding. Alibaba owns the South China Morning Post.In December, StairMed unveiled the programme – undertaken in partnership with a research team at the Chinese Academy of Sciences – to insert BCIs via blood vessel into a targeted region of the brain and anchor them in place outside the vessel wall. So far, it has tested the technique on sheep, but has yet to begin human trials.The BCI implant device market is projected to grow rapidly over the next decade, and be worth US$80 billion in the United States alone by 2035, according to a Morgan Stanley report. China has vowed to nurture “two or three” global players in the sector by 2030.A surgeon with four or five years of experience can position the device in as little as 10 minutesDuan Wanru, Xuanwu Hospital
