Core Viewpoint - Brain-computer interface (BCI) technology is advancing rapidly, enabling direct communication between the brain and external devices, with significant implications for medical rehabilitation and beyond [3][19]. Group 1: Technology Overview - BCI technology establishes a connection between the brain and external devices, allowing for the control of actions through thought [3]. - The latest development, "Lingxi Finger," is being tested in laboratories, showcasing the ability to control a mechanical finger using brain signals [3][7]. - A domestically developed brainwave acquisition chip has achieved performance comparable to international commercial chips, with plans for domestic use by the end of this year or early next year [11]. Group 2: Applications in Healthcare - BCI technology is being applied in medical settings, particularly for stroke rehabilitation, enhancing recovery efficiency by decoding motor intentions from brain signals [7][19]. - New BCI devices are being used for real-time intracranial pressure monitoring, reducing the need for invasive procedures [17]. - Over ten types of BCI devices are currently in clinical trials for various neurological conditions, indicating a growing integration of research and clinical application [19]. Group 3: Industry Development - The Chinese government is actively promoting the BCI industry through policies and action plans, establishing a foundational industry chain from electrodes and chips to software and applications [21]. - The industry is evolving with a focus on mixed intelligence and brain-like intelligence, which could lead to new applications in neuro-rehabilitation and artificial intelligence [15].
