复旦大学“纤维芯片”刷屏！有望成脑机接口重要支撑

Core Viewpoint - Fudan University has developed a groundbreaking "fiber chip" that breaks the traditional silicon-based chip paradigm, enabling advanced applications in brain-machine interfaces, electronic textiles, and virtual reality [1][5]. Group 1: Research and Development - The research was led by Professor Peng Huisheng and Professor Chen Peining, with support from various national and local scientific funding bodies [5]. - The paper titled "Fiber Integrated Circuits Based on Multi-layer Stacking Architecture" was published in the journal Nature [1]. Group 2: Technical Innovations - The "fiber chip" maintains the intrinsic properties of fibers, such as flexibility and weavability, while achieving high-precision interconnections of electronic components like resistors, capacitors, diodes, and transistors [7]. - A 1mm long "fiber chip" can integrate tens of thousands of transistors, with potential to reach millions if extended to 1 meter, comparable to traditional computer processors [7][8]. Group 3: Applications in Brain-Machine Interfaces - The "fiber chip" can potentially overcome limitations of traditional devices in brain-machine interfaces, providing new tools for brain science research and treatment of neurological diseases [8]. - Initial experiments show that the fiber can integrate a high-density array of electrodes and signal processing circuits, achieving a signal-to-noise ratio of 7.5 dB, comparable to commercial devices [8][9]. Group 4: Applications in Electronic Textiles and Virtual Reality - The "fiber chip" can transform ordinary clothing into interactive displays, allowing for real-time health data display and video playback without external devices [11]. - In virtual reality, the fiber chip enables the development of smart haptic gloves that can accurately simulate touch sensations, enhancing remote surgical procedures and gaming experiences [11][12]. Group 5: Future Prospects - The research team aims to enhance interdisciplinary collaboration and industrial partnerships to improve chip yield and integration, facilitating high-quality applications of the "fiber chip" across various fields [12][13].
