比马斯克Neuralink工艺更先进！我国成功开展首例侵入式脑机接口临床试验

Core Viewpoint - The article discusses the successful clinical trial of an invasive brain-computer interface (BCI) in China, marking a significant advancement in the field and positioning China as the second country globally to enter this stage after Neuralink. Group 1: Clinical Trial and Technology - The clinical trial was conducted by the Chinese Academy of Sciences in collaboration with Fudan University Huashan Hospital and related enterprises [2] - The trial involved a 37-year-old male who, after a severe accident leading to limb loss, can now control a computer interface using only his thoughts [27][28] - The implanted neural electrodes are the smallest and most flexible globally, with a size comparable to a coin and a flexibility exceeding that of Neuralink's products by over 100 times [4][12][10] Group 2: Technical Innovations - The team utilized semiconductor processing technology to minimize damage to brain tissue, achieving a design that is both small and soft [8][15] - The new neural electrodes have a cross-sectional area that is 1/5 to 1/7 of Neuralink's electrodes, ensuring long-term stability and functionality [10][21] - The device has a projected lifespan of 5 years, with the potential for upgrades through secondary surgeries [22][33] Group 3: Future Applications - Short-term goals include enabling users to control robotic arms for physical tasks like grasping and holding objects [6][7] - Long-term aspirations involve controlling complex physical devices, such as robotic dogs and intelligent robots, thereby expanding the boundaries of daily life [7] - The research aims to significantly improve the quality of life for individuals with complete spinal cord injuries, amputations, and amyotrophic lateral sclerosis [34]
