NeuroXess completes China's first fully implanted, battery-powered brain-computer interface in clinical trial
NeuroXess completed the implantation of a fully wireless, battery-powered BCI in a 28-year-old patient with spinal cord injury, the second company globally to achieve this after Neuralink. Within five days of activation, the patient controlled a computer cursor via thought alone and could operate a wheelchair and robotic arm. The device uses a chest-implanted battery and flexible electrode arrays for wireless signal transmission.
- Patient achieved 5.2 bits per second neural decoding, enabling dozens of commands per minute.
- Fully implanted device recovered quickly; patient discharged to general ward one day after surgery.
- Wireless architecture (battery and electrodes) avoids infection-prone percutaneous connectors.
- Flexible electrodes and chest-mounted battery design reduce heat and infection risk near the brain.
