Core Insights - China's first invasive brain-computer interface (BCI) clinical trial has been successfully conducted, making it the second country globally to enter this phase after the United States [1] - The trial involved a 37-year-old male subject who lost his limbs due to an electrical accident, and he was able to control a computer touchpad through thought after 2-3 weeks of training [1][2] - The developed flexible neural electrodes have a small cross-sectional area and high flexibility, reducing damage to brain tissue [1][2] Group 1 - The BCI device implanted has a diameter of 26mm and a thickness of less than 6mm, allowing for a minimally invasive surgical procedure [2] - The implantation process involves creating a small groove in the skull and inserting ultra-flexible neural electrodes into the brain tissue, taking only 20-30 minutes [2] - The electrodes are designed to collect neural signals accurately by being placed close to the brain's motor cortex [2][3] Group 2 - Precise positioning and implantation are critical for the success of the surgery, achieved through advanced imaging techniques [3] - The research team plans to enable the subject to control a robotic arm for physical tasks, expanding the application of the BCI technology [3]
