新突破！我国侵入式脑机接口临床试验实现三维物理世界操控与交互

Core Viewpoint - The recent clinical trial of an invasive brain-computer interface (BCI) in China marks a significant advancement, transitioning from 2D control to 3D interaction with the physical world, enhancing the quality of life for patients with severe disabilities [1][5][11] Group 1: Clinical Trial Details - The trial involved a middle-aged male patient who suffered from quadriplegia due to spinal cord injury, with limited movement capabilities [1] - After implantation of the BCI system in June 2025, the patient was able to control electronic devices using thought within 2 to 3 weeks of training, similar to the first trial's outcomes [3] - The BCI system has now expanded its application from 2D screens to 3D physical interactions, allowing the patient to control devices like wheelchairs and robotic dogs with minimal latency [5][7] Group 2: Technical Aspects of the BCI - The BCI system consists of a front-end sensor, which is a fine wire inserted into the brain, and a back-end processor embedded in the skull, making the procedure minimally invasive [11][13] - The front-end sensor connects the brain to the external world, while the back-end processor converts neural activity into digital signals for device control [13][15] - The system features continuous, stable, and low-latency control, with advancements in neural data compression technology improving performance by 15% to 20% even in noisy environments [20] Group 3: Future Applications and Innovations - The research team is exploring further applications, including decoding language information from the brain and expressing internal intentions through external devices [19] - Key technologies such as cross-day stability and online recalibration have been developed to enhance user experience, allowing real-time adjustments to decoding parameters [20] - The end-to-end latency of the system has been reduced to under 100 milliseconds, providing a seamless control experience for the user [20]
