China is showcasing its latest advances in brain-computer interface (BCI) technology at the 2025 Shenzhen BCI & Human-Computer Interaction Expo. The event also launched a new AI innovation alliance for brain science and central nervous system diseases, focusing on neurological drug innovation, BCI, and AI-powered medical solutions.
An 11.6-billion-yuan ($165 million) brain science fund was unveiled to support companies from research to commercialization. Chinese researchers recently completed the country’s first and the world’s second fully implanted, wireless BCI clinical trial, allowing patients with high-level spinal injuries to control external devices using brain signals alone without external equipment.
Beyond motor recovery, researchers are exploring visual reconstruction using implanted BCIs, introducing closed-loop feedback to improve perception. The system can restore basic vision functions, such as obstacle detection, marking a significant step toward real-world clinical applications and the broader commercialization of BCI technologies in China.
