复旦大学研究人员研发出“纤维芯片”，可集成数万个晶体管

Core Viewpoint - Fudan University has developed a "fiber chip" that integrates multiple electronic functions into a single polymer fiber, marking a significant advancement in flexible electronics and opening new pathways for fiber electronic systems [1][3]. Group 1: Technological Breakthrough - The "fiber chip" maintains the intrinsic properties of flexibility and weavability while achieving high-precision interconnections of electronic components such as resistors, capacitors, diodes, and transistors [3]. - The light lithography precision of the "fiber chip" reaches the highest level of laboratory-grade lithography machines, allowing for the integration of light-emitting and sensing modules directly into a single fiber [3]. Group 2: Potential Applications - This technology is expected to provide strong technical support for emerging industries such as brain-machine interfaces, electronic textiles, and virtual reality [3]. - In the field of brain-machine interfaces, the ultra-fine "fiber chip" could integrate high-density electrodes and preprocessing circuits, leading to the development of softer and more biocompatible neural probes [4]. Group 3: Performance Metrics - Experimental estimates suggest that a 1-millimeter long "fiber chip" can integrate tens of thousands of transistors, with information processing capabilities comparable to some medical implantable chips [3]. - If the length of the "fiber chip" is extended to 1 meter, the number of integrated transistors could reach millions, achieving integration levels comparable to classic computer central processing units [3].
