帮助高位截瘫患者稳定操控智能轮椅与机器狗我国侵入式脑机接口技术迎来新突破

Core Insights - The article discusses the successful completion of China's second invasive brain-computer interface (BCI) clinical trial, enabling a high-level paraplegic patient to control a smart wheelchair and robotic dog using brain signals [1][6][8]. Group 1: Clinical Trial Achievements - The second invasive BCI trial demonstrated the ability of a patient with high-level paraplegia to control devices in real-life scenarios, marking a significant advancement from previous trials focused on electronic device control [8]. - The patient, who suffered from spinal cord injury, underwent training that allowed him to control devices with minimal delay, achieving a control experience that felt natural and intuitive [8][9]. Group 2: Technological Innovations - The research team developed a high-compression, high-fidelity neural data compression technology, improving brain control performance by 15%-20% even in noisy environments [6][7]. - Innovations included "neural manifold alignment technology" to enhance stability in real-world environments and "online recalibration technology" for continuous system optimization during use [7][9]. Group 3: Future Developments - The team has announced an upgraded BCI system (WRS02) with enhanced capabilities, including an increase in channel count to 256, with the first clinical trial planned soon [9]. - Future applications of BCI technology are expected to expand into areas such as sensory restoration and precise control of neurological disorders within the next five years [12][13]. Group 4: Societal Impact - The research team is collaborating with local disability organizations to enable patients to participate in online data annotation work, transforming them from recipients of care to contributors to society [10][12]. - The integration of BCI technology with external smart devices is seen as crucial for enhancing patient quality of life and achieving broader societal benefits [12].
