NeuroXess completes China's first fully implanted battery-integrated BCI — patient controls cursor in 5 days
Summary
Shanghai-based NeuroXess completed China's first human implantation of a fully battery-integrated BCI in December 2025, performed at Huashan Hospital affiliated with Fudan University. The 28-year-old patient — paralyzed below the shoulders for 8 years — achieved cursor control within 5 days, later operating a wheelchair and robotic arm. NeuroXess's system achieved 5.2 bits/second decoding — near leading international levels. All core modules including the battery are fully implanted; no external cables or ports are required. The company has now completed 54 total BCI implantations.
Why it matters
China joining the fully implanted wireless BCI club — alongside Neuralink — with competitive decoding rates and 54 clinical implantations represents a major shift in the global BCI competitive landscape. NeuroXess's surface mesh approach (no penetrating electrodes) is a genuinely differentiated technical strategy that sidesteps Neuralink's electrode scarring concerns.
