NeuroXess has achieved a landmark clinical breakthrough with China’s first fully implanted, wireless, full-function brain–computer interface, turning thought-based control into reality.
December 13, 2025 — At the 2025 Tsinghua Brain Science Institute Forum on Brain–Computer Interfaces and Artificial Intelligence, NeuroXess announced the successful completion of the first clinical trial of its self-developed “triple-full” brain–computer interface (BCI)—fully implanted, fully wireless, and fully functional—at Huashan Hospital affiliated with Fudan University.
This milestone places China among the world’s top tier of BCI innovators. The device is also China’s first and the world’s second brain–computer interface system to feature a built-in battery.
The trial participant was a 28-year-old man who had lived with high-level spinal cord injury for eight years. Just one day after surgery, he was transferred from the ICU to a general ward. On day five post-operation, during his first activation and training session, he successfully achieved thought-based control, smoothly completing tasks such as web browsing, precise clicking, and video playback. In subsequent sessions, he was able to control a smart wheelchair, play video games, and even defeat NeuroXess founder and chief scientist Tao Hu in a game match using only his thoughts.
The system achieved a brain-control decoding rate of 5.2 bits per second (BPS), comparable to leading international standards.

The product’s advantages lie in its groundbreaking “triple-full” design:
- Fully implanted: All core modules, including the battery, are implanted inside the body. Innovatively, the battery is placed subcutaneously in the chest, away from the brain to minimize heat risks and eliminate infection hazards associated with externalized systems.
- Fully wireless: Wireless power supply and data transmission free patients entirely from external devices.
- Fully functional: Multiple modules are integrated into a single system, powered by NeuroXess’s proprietary plug-in operating system, XessOs, which can connect to devices such as pneumatic gloves, smart home systems, and humanoid equipment, enabling an ecosystem of “extended embodiment.”

In addition, the NeuroXess team has deeply integrated AI foundation models into its BCI system, achieving key breakthroughs in real-time speech decoding. This progress lays critical groundwork for restoring communication abilities in patients with speech impairments.
Founder Tao Hu noted that the achievement validates a technological path that is safer, more open, and more human-centered. It highlights China’s growing global competitiveness in brain–computer interfaces and reflects a strong commitment to using cutting-edge technology to improve the lives of patients with neurological disorders.
