On September 1, 2025, at 3:00 p.m., Professor Wang Gang from the School of Materials Science and Engineering at Donghua University, invited by Professor Huang Hui, delivered a lecture titled “Semiconductor Functional Fibers and Fabric Electronic Systems” at the University of Chinese Academy of Sciences, Yanqi Lake Campus, Room 114 of Academic Building 2.

Professor Wang Gang, Deputy Dean and Researcher at the State Key Laboratory of Advanced Fibrous Materials and the School of Materials Science and Engineering, Donghua University, is the project leader of the National Key R&D Program. He has received the National New Era Youth Pioneer Award, the First Prize for Teaching Achievements from the China National Textile and Apparel Council, the Outstanding Contribution Award for Industry-Academia-Research Cooperation from Glory Group, and the Shanghai Youth May Fourth Medal. He was also selected for the Ministry of Organization’s National Young Thousand Talents Program and the Shanghai Technology Youth 35 Leaders Plan. In the past five years, he has published 15 academic papers in journals such as Nature Materials, PNAS, Chemical Reviews, and Nature Communications, been granted 10 Chinese invention patents, and built the first continuous production line for semiconductor superstructure fibers with a capacity of grams per minute. He serves as Executive Secretary-General of the International Advanced Fibrous Materials Society and Executive Editor of the Q1 journal Advanced Fiber Materials. He has presided over major national projects such as the National Key R&D Program and the National Natural Science Foundation’s Major Research Plans. He also led the establishment of a major university-enterprise joint research platform, the “Starry Sky Laboratory,” whose fabric electronic products have been applied in active health monitoring, energy pipeline networks, and technological Olympic equipment.

At the beginning of the lecture, Professor Wang emphasized that with the rapid development of semiconductor polymers, fibers and textiles integrated with electronic functions are emerging, showing great potential in brain-machine interfaces, health monitoring, and portable computing. These materials are especially promising for wearable and implantable applications. A key scientific challenge, however, lies in fabricating one-dimensional fibrous semiconductor devices from high-dimensional semiconductors while preserving their inherent properties.

Professor Wang then elaborated on his team’s approaches to overcoming these challenges, which include:

1. Proposing a novel design concept of “microfluidic shear field–induced semiconductor fiber formation,” enabling precise microfluidic control to finely tune composition, interfaces, and orientation during the spinning process.

2. Improving lithography techniques to transfer precise patterns onto fiber surfaces, thereby fabricating high-performance circuits such as fiber-shaped diodes and transistors.

3. Developing semiconductor fiber integration strategies such as “lithography-weaving” and “topological-weaving,” which have been successfully applied in active health systems, West-to-East Gas Transmission pipeline monitoring, and critical equipment for technological Olympics.

Finally, Professor Wang’s presentation sparked deep reflection, lively exchanges, and discussions among the faculty and students in attendance. The participants all agreed that they gained invaluable insights from the lecture.
