Prof. Xu Bingang’s team publishes in Advanced Energy Materials

Rapid technological advancements have reduced the size and increased the portability of electronics. In 2021, the number of portable devices reached 12.2 billion globally, and is predicted to exceed 25 billion in 2025. Such an immense number of small electronics has resulted in an ever-increasing demand for energy. However, existing energy sources are primarily derived from unsustainable resources such as coal, oil and natural gas, which are non-renewable and cause pollution. Therefore, developing renewable and sustainable types of energy is an important, urgent, albeit challenging task. Prof. Xu Bingang’s research focuses on an important direction: determining how to provide a green, renewable and sustainable power supply for wearable electronic devices. To tackle this issue, his team has carried out avant-garde research on utilising human motions like walking and running, and environmental sources like sunlight, heat and humidity, to convert mechanical, solar, thermal and humidity energy into usable electric energy for sustainable applications. The works are based on the individual energy-conversion effects of piezoelectric, triboelectric, photoelectric, thermoelectric, and moist-electric effects. To further enlarge the input energy capacity for higher performance, his team has also made effort to combine or integrate these energy-conversion effects by developing a kind of hybrid energy harvester that is able to harvest renewable energies from multiple sources simultaneously (like mechanical, solar, moisture and thermal energy) and then convert them into electricity. The main challenges for developing this kind of hybrid energy harvesting method lies in the fundamental study and novel designs of functional materials that can effectively resolve the problem of synergistic coupling and fusion of different input energies into a single device unit. More recently, Prof. Xu’s team has made an innovative breakthrough in the field by fundamentally disclosing and designing a new type of hybrid multi-energy harvesting strategy. This development is based on their new understanding and synergistical regulation of charge generation and transfer dynamics by integrating ferroelectric and photovoltaic effects with the tribovoltaic effect. With this new strategy, the developed multi-energy devices are flexible for wearing and can also deliver an impressive direct current (DC) electric output of 7.3 V and 69.8 µA, thus outperforming those in other reported works. In addition to driving portable devices, the flexible multi-energy harvesting device is also capable of self-powered multifunctional sensing, including sensing temperature, humidity, bending, and photodetection. This study proposes new scientific insights into modulating the electric performance of hybrid energy harvesting while extending its functionality to applications in smart wearables and e-textiles. This work is published in Advanced Energy Materials (https://onlinelibrary.wiley.com/doi/10.1002/aenm.202402145), a top-tier journal in Materials Science with an impact factor of 24.4. The first two authors are respectively Drs Xin Yin and Yujue Yang, a postdoctoral fellow and a new PhD graduate (2024) under the supervision of Prof. Xu.

Dr Fan Di receives media attention for publication

Dr Fan Di, Associate Professor, has published a significant study titled "Locking in Overseas Buyers Amid Geopolitical Conflicts" in the Journal of Operations Management. This collaborative research, conducted with scholars from Renmin University, the Australian National University, and Singapore Management University, explores the impact of the ongoing U.S.–China trade war on cross-border trade relationships. The study reveals that transactions between U.S. buyers and Chinese suppliers dropped by 18.42% following the 2018 trade war. It also highlights strategies for mitigating these impacts, emphasising the importance of innovation and corporate social responsibility (CSR) in building resilient international relationships. The study provides essential insights for businesses that are navigating today’s deglobalised world. Dr Fan and his team suggest that Chinese suppliers with strong innovation capabilities and high CSR performance are better equipped to retain overseas buyers. Furthermore, while political connections can be beneficial during stable times, they may become liabilities amid geopolitical tensions, thus posing risks to international partnerships. Buyers, on the other hand, should carefully assess their dependence on specific suppliers and strive to balance supplier capabilities with supply chain flexibility to enhance resilience against geopolitical risks. The importance of Dr Fan's research work has caught the attention of major media outlets, including the South China Morning Post and Asia Times. An article in the South China Morning Post, "Is Vietnam losing its appeal for China’s manufacturers bypassing US tariffs?," examines how Chinese firms adapt their strategies amidst changing geopolitical dynamics. Similarly, the Asia Times discusses the ongoing challenges faced by Chinese EV manufacturers in "China EVs still driving for EU’s protected markets." These features underscore the relevance and impact of Dr Fan’s work, which offers a comprehensive analysis of the strategies that businesses can use to navigate the complexities of geopolitical conflicts. The Journal of Operations Management is a flagship peer-reviewed academic journal in the area of operations and supply chain management. It is listed in the Financial Times 50 and UT-Dallas journal lists, and ranked 4* on the UK’s ABS journal list and A* on Australia’s ABDC list. The full article is available here.

Dr Shou Dahua develops intelligent activewear for a dry and comfortable experience

The Paris 2024 Summer Olympic Games are just around the corner and a global sports frenzy is underway. However, intense summer workouts often lead to sportswear absorbing excessive sweat, becoming clingy and cumbersome, causing discomfort and potentially impacting performance. Limin Endowed Young Scholar in Advanced Textiles Technologies and Associate Professor, Dr Shou Dahua has developed the iActive™ sportswear range which features a root-like liquid transport system and a skin-like active perspiration dissipater and utilises nature-inspired, anti-heat textile fabrics to expedite sweat removal, effectively reducing the weight and stickiness of activewear caused by sweat accumulation during exercise. The human body has millions of sweat glands that are vital for regulating body temperature by dissipating sweat for evaporation to cool the skin’s surface. With unabating greenhouse gas emissions, the number of very hot days annually is expected to increase significantly. This will lead to elevated energy consumption and increased sweating during physical activity and outdoor labour. Even when wearing highly breathable clothes with good sweat-wicking properties, individuals may still experience discomfort due to excessive sweat accumulation. A research team led by Dr Shou, has invented the groundbreaking iActive™, intelligent, electrically activated sportswear with a nature-inspired active perspiration function. This pioneering innovation has garnered significant recognition, including a Gold Medal at the 49th International Exhibition of Inventions Geneva this April. Its nature-inspired technologies, including low-voltage-driven artificial “sweat glands” created by skin-like anti-heat textile fabrics and a root-like branching liquid transport system that aligns with the body’s sweat map, can actively and programmably transport sweat to a perspiration dissipater at the lower region of the sportswear, and quickly remove it as liquid droplets. The all-textile sweat dissipater is compact and operates at a safe output voltage of approximately 5-9V, and its battery is easy to detach from the clothing, making it convenient for users to repeatedly wash the clothing by hand or in a washing machine to maintain hygiene. When the human body’s sweat rate is low, iActive™ can still be used independently without the battery. Based on the optimised wettability pattern and gradient, the research team utilises a skin-like textile fabric to transport sweat one-way quickly and dissipate it directionally from the inside to the outside. This feature reduces the stickiness and weight of clothing, improves breathability and ensures the garments remain dry and comfortable to wear. Experimental findings indicate that iActive™ creates a breathable and dry skin microclimate by dissipating sweat at a rate that is three times faster than the maximum human sweating rate. This innovation can also prevent discomfort from coldness and moisture after a workout. In comparison to traditional fabrics, the textile materials in iActive™ are 60% lighter and 50% less clingy when soaked, providing the wearer with all-round comfort and enabling sports enthusiasts and athletes to perform at their best. Furthermore, a mobile app further aids personalised sweat management by wirelessly adjusting the sweat level of iActive™. This innovation is versatile and can be seamlessly integrated into a variety of textile materials to facilitate sustainable mass production. Beyond sportswear, iActive™ is also well-suited to protective clothing and workwear for individuals engaged in prolonged, high-intensity physical labour and outdoor occupations, including healthcare professionals, construction workers, firefighters, law enforcement officers and others, thereby significantly enhancing their work performance. Dr Shou stated, “The extreme weather and high temperatures resulting from global warming have elevated the importance of heatstroke prevention and cooling measures on a global scale. Drawing on the vivid phenomena of thermal insulation and directed liquid flow in nature, we aim to foster innovation and sustainable advancement in garment manufacturing by inventing intelligent clothing and materials to address global challenges. We seek to harness the power of technology to infuse fresh perspectives into the traditional clothing industry, thereby enhancing its competitiveness.” His research team has also developed a premium fabric named Omni-Cool-Dry™, drawing inspiration from volcano dwelling beetles. This fabric not only provides ultra-fast sweat dissipation and ensures all-day comfort with its dry and breathable features under dynamic thermal conditions, but also reflects solar radiation and emits body heat into the cold universe, enabling passive cooling. The team is working hard to leverage the benefits of both inventions to further enhance the sweat-dissipating and cooling capability of iActive™ sportswear. Dr Shou, a core member of the PolyU Research Institute for Intelligent Wearable Systems and the Research Centre of Textiles for Future Fashion, has recently been bestowed with the 2023 Distinguished Achievement Award by The Fiber Society for his outstanding contributions to the fields of personal thermal and moisture management, intelligent wearables and soft robotics. The accolade is presented annually to an individual researcher worldwide. He has also received international innovation awards, including consecutive TechConnect Global Innovation Awards in 2021 and 2022. Moreover, his research papers have been published in various internationally renowned academic journals including Science Advances, PNAS, Advanced Functional Materials, and Advanced Energy Materials. Dr Shou will be chairing The Fiber Society Spring 2025 Conference at PolyU.

Prof. Christina Wong conferred as RGC Senior Research Fellow and awarded fellowship grant of HK$8 million

SFT is thrilled to announce that Professor Christina Wong is an awardee of the highly competitive RGC Senior Research Fellow Scheme (SRFS) 2024/25 offered by the Research Grants Council (RGC) for excellence in research on the circular economy for global sustainable production and consumption.  This year, the RGC selected 10 nominees among 38 nominations for the SRFS awards. Professor Wong has been conferred the title "RGC Senior Research Fellow" and PolyU will receive a fellowship grant of around HK$8 million for her 5-year research project titled “Beyond Regulatory Exertion: Circular Economy Governance, and its Institutionalization and Performance Impacts”. The circular economy represents a model of production and consumption in which products and materials are cycled back into the economy until the end of their useful life, thereby reducing global material extraction. However, only 7.2% of global resources that enter the market are recovered and recycled annually, according to the Circularity Gap Report published at the World Economic Forum in 2023. Despite government efforts in setting action plans and policies on the circular economy, collective industrial efforts are essential for monitoring and controlling waste and resource efficiency. Considering the knowledge gap on circular economy governance and its benefits, the research addresses this challenge by demonstrating how different business conditions affect governance performance in the circular economy, and subsequently driving the establishment of circular economy governance. Professor Wong said, “Receiving this funding award greatly contributes to my research work on sustainable goals for responsible consumption and production. The exceptional capacity of PolyU, and its academic and research expertise, specialised facilities, and interdisciplinary resources have extensively supported our research, thus empowering us to generate profound societal impacts.” The RGC SRFS aims to provide sustained support and relief from teaching and administrative duties to exceptionally outstanding researchers at the Associate Professor rank (or full Professor rank) of UGC-funded universities in Hong Kong, with the view to facilitate their full dedication to research and development and help universities attract and retain research talent.
