　　 The 2024 Science and Technology Award of China Textile Industry Federation was announced recently. The project of "Energy and Humidity Management Function Regulation of Electromechanical Conversion Fibers and Fabrics" (hereinafter referred to as "Electromechanical Conversion Project"), developed by Professor Wang Hongzhi, School of Materials, Donghua University, as the first person to complete the project, won the first prize of Natural Science Award. The project has achieved a double breakthrough in the field of smart fibers, creating a new way for energy conversion of fiber materials and human body heat and humidity management.

　　 Clothing is known as the "second skin" of human beings. However, it is often difficult for traditional fabrics to intelligently sense temperature changes and make timely adjustments like human skin. "This technology has opened up the whole chain of" perception, energy supply and regulation "of intelligent fabrics, and realized the collaborative design of energy conversion and damp heat regulation on the fiber scale." Wang Hongzhi, the project leader, said that electromechanical conversion fiber is like an intelligent personal assistant, undertaking multiple tasks of perception, regulation and protection, and always guarding the comfortable experience of the wearer. The electromechanical conversion project is led by Donghua University. After five years of exploration, it has made many original achievements in fiber structure design, performance control and other aspects, established a cross scale structure-activity relationship from fiber to fabric, and formed a core technology system with independent intellectual property rights. Relevant research achievements have published several papers in top international journals such as Science, Nature Communication, Advanced Materials, and won several national invention patents, reaching the international leading level. This achievement not only achieved a major breakthrough in the field of electromechanical conversion fiber, but also laid a foundation for the future development of all-weather, intelligent functional clothing.

　　 Technical breakthrough: a long way from imagination to realization

　　 In scientific research, accidental phenomena often contain breakthrough opportunities, and the key lies in whether the hidden laws can be captured. In 2020, Professor Wang Hongzhi's team accidentally captured an abnormal noise signal in the electrical signal test of friction nano power generation fabric. It was initially considered as a phenomenon of experimental interference. After in-depth study, it gradually revealed a new physical mechanism - the characteristics of plasma frequency in electrostatic discharge. This discovery not only verified the new mechanism of human energy coupling, but also promoted the breakthrough of electromechanical conversion fiber technology for synchronous transmission of wireless energy and signal. This achievement breaks through the bottleneck of independent energy supply for intelligent fabrics, and also provides a new idea for the multi-functional design of textiles.

　　 However, this is just a slice of Wang Hongzhi's team's more than ten years of intelligent clothing research. From energy management to hydrothermal regulation, from sensing response to deformation and color change, they have always carried out systematic research around the core functional requirements of smart textiles, and constantly promoted technological innovation based on material science. In terms of energy management, the team has developed fiber power generation technology based on electrostatic effect, providing a reliable independent energy supply scheme for smart clothing; In the field of humidity and heat control, they optimized the microstructure of fibers, and tested the material performance in simulated extreme environments, improving the comfort and practicality of smart clothing; Sensing and color changing technologies have given more possibilities to intelligent fabrics, enabling them to be widely used in environmental monitoring, physiological signal capture, dynamic appearance adjustment and other fields.

　　 "There is no shortcut in scientific research, and all accumulation needs to be consolidated a little bit." Through these studies, team members are dedicated to details and rooted in practice. They overcame the limitations of experimental conditions and independently designed equipment to verify assumptions; Faced with the challenge of complex environment, the material performance was repeatedly tested in the high-temperature and humid outdoor environment, and the test equipment and recording data were shuttled back and forth every day, with a group of detailed data supporting the deduction and correction of scientific assumptions. From the breakthrough of basic theory to the landing of large-scale preparation technology, each progress is full of challenges, but it also paves the way for the next innovation.

　　 In 2024, Professor Wang Hongzhi won the highest honor in China's textile industry - mulberry and hemp scholar award with his important research achievements in the field of smart fibers. Behind this award is more than ten years of tireless exploration and practice, the persistence and breakthrough in countless experiments, and the enthusiasm and focus on the unknown fields.

　　 Achievement transformation: fiber revolution from laboratory to industrialization

　　 The end point of scientific research is not only laboratory, but also practical application and industrialization. In order to transform the electromechanical conversion fiber technology from research achievements to practical products, Professor Wang Hongzhi's team, together with several enterprises, has built a large-scale industrial production line of electromechanical conversion fiber with independent intellectual property rights. The successful operation of this production line has laid the foundation for bringing the advanced fiber technology of the laboratory to the market, and significantly improved the efficiency and consistency of textile manufacturing.

　　 Based on the technical achievements of the production line, the team cooperates with Shanghai International Fashion Science and Technology Innovation Center, Shanghai Style Fashion Design and Value Creation Collaborative Innovation Center, Shanghai International Fashion Creative College, Textile College, Fashion and Art Design College, Information Science and Technology College, etc. to jointly develop scientific and technological cheongsam. By embedding sensing, deformation and discoloration fibers, real-time monitoring, dynamic fusion of morphological changes and visual effects are realized. This series of cheongsam not only integrates modern intelligent technology into traditional clothing culture, but also becomes a model of the combination of wearing aesthetics and high-tech functions. Its innovative design was unveiled at the Edinburgh Art Festival, and was presented at the 70th anniversary achievement exhibition of the founding of New China as a landmark achievement of China's textile industry, fully demonstrating the deep integration of traditional textile technology and modern intelligent technology. In addition, in the field of sportswear and medical protective clothing, the team has developed products with both functionality and comfort by improving the performance of fabric moisture and heat management. These cooperation fully shows that electromechanical conversion fiber technology is not only a breakthrough in the laboratory, but also is promoting the traditional textile industry to move towards intelligent and functional direction.

　　 The most eye-catching is a kind of light-emitting fiber technology developed by the team that integrates energy collection, signal emission and light-emitting display. This kind of fiber adopts a non Von Neumann architecture. Through the deep combination of energy coupling and wireless signal transmission, it has achieved an important breakthrough from functional design to integrated innovation. The light-emitting fiber can not only run efficiently in complex environments, but also has flexible customizable characteristics, which can be applied to multiple scenes such as intelligent clothing, underwater rescue and dynamic identification. Its unique performance and wide application potential were described in detail in the research paper published by the team in Science. At the same time, this technology was also rated as one of the top ten scientific and technological achievements in the textile field.

　　 Inheritance prospect: salute the future with original intention

　　 Through years of unremitting efforts, Professor Wang Hongzhi's team has made a series of important breakthroughs in the field of intelligent textiles. Focusing on the core technology of electromechanical conversion fiber, they not only realized the leap from laboratory to large-scale production, but also carried out innovative research in the fields of intelligent color development and color change, thermoelectric and triboelectric energy conversion devices, lithium electricity and zinc air flexible energy storage devices, and human-computer interaction textiles. These efforts have promoted the wide application of smart fiber technology in smart wearable devices, health monitoring, human-computer interaction and other fields, and provided important support for future industrial development.

　　 Since 2024, the team has published many papers in Science, Science Advanced, Nature Communications (3), Advanced Materials (2), Advanced Functional Materials (5), Material, Device (2) and other journals. These studies not only highlight the leading position of Donghua University in the field of intelligent textile technology, but also inject new momentum into the technological innovation of related industries.

　　 Since its establishment, Donghua University has always been deeply integrating scientific and technological innovation with serving the society, and has written a history of struggle to help the national development with textile technology. From overcoming the problem of "difficult to dress" in the early days of the founding of New China, leading the technological upgrading of the textile industry after the reform and opening up, and now expanding the future industrial space with intelligent textile technology, the scientific research pace of Donghua University has always been closely linked to the development of the times.

　　 In different historical stages, Donghua University has practiced its original intention of "serving the country with textiles" with practical actions. From developing high-performance military clothing to meet the needs of cold regions, to promoting the popularity of civil protective fabrics, to supporting the textile industry to move towards green and intelligent transformation, each breakthrough embodies the wisdom and painstaking efforts of several generations of Donghua people. This award-winning project is the continuation of this spirit in the new era - it takes science and technology as the link, organically combines traditional textile technology with modern intelligent technology, and points out the direction for the future of the textile industry.
