PolyU researchers invent intelligent soft robotic clothing for automatic thermal adaptation in extreme heat

Dr Dahua SHOU, Member of the Research Institute for Intelligent Wearable Systems (RI-IWEAR), the Research Institute for Sports Science and Technology (RISports) and the Research Centre of Textiles for Future Fashion (RCTFF), Limin Endowed Young Scholar in Advanced Textiles Technologies and Associate Professor in the School of Fashion and Textiles, and his team have developed a first-of-its-kind thermally-insulated and breathable soft robotic clothing that can automatically adapt to changing ambient temperatures, thereby helping to ensure worker safety in hot environments. Their research findings have been published in the international interdisciplinary journal Advanced Science. The protective clothing developed by the team uses soft robotic textile for dynamic adaptive thermal management. Soft actuators, designed like a human network-patterned exoskeleton and encapsulating a non-toxic, non-flammable, low-boiling-point fluid, were strategically embedded within the clothing. This thermo-stimulated system turns the fluid from a liquid into a gas when the ambient temperature rises, causing the expansion of soft actuators and the thickening of the textile matrix, thereby enhancing the gap of still air and doubling the thermal resistance from 0.23 to 0.48 Km²/W. The protective clothing can also keep the inner surface temperatures at least 10°C cooler than conventional heat-resistant clothing, even when the outer surface reaches 120°C. This unique soft robotic textile, made by thermoplastic polyurethane, is soft, resilient and durable. Notably, it is far more skin-friendly and conformable than temperature-responsive clothing embedded with shape-memory alloys and is adjustable for a wide range of protective clothing. The soft actuators have exhibited no signs of leakage after undergoing rigorous standard washing tests. The porous, spaced knitting structure of the material can also significantly reduce convective heat transfer while maintaining high moisture breathability. Not relying on thermoelectric chips or circulatory liquid cooling systems for cooling or heat conduction, the light-weighted, soft robotic clothing can effectively regulate temperature itself without any energy consumption. The innovation will have a wide range of potential applications, from activewear, winter jackets, healthcare apparel and outdoor gear, to sustainable textile-based insulation for construction and buildings, contributing to energy-saving efforts. In addition, with funding support from the Innovation and Technology Commission and the Hong Kong Research Institute of Textiles and Apparel, the research team has extended the thermo-adaptive concept to develop inflatable, breathable jackets and warm clothing. This soft robotic clothing is suitable for low-temperature environments or sudden temperature drops to aid those who are stranded in the wilderness to maintain normal body temperature.

RiFood study finds lactating women eating not enough fruit and vegetables

A study by the Research Institute for Future Food (RiFood) has found that breastfeeding women in Hong Kong are not eating enough fruit and vegetables according to the recommended level by the Department of Health, although the intake has increased significantly over the past 10 years. From mid-2022 to mid-2024, the research team collected the dietary records of more than 80 lactating women and measured their weight and blood lipid levels. The study found that, compared with a similar survey in 2014, the intake of vegetables, dietary fibre and vitamin A increased by 34%, 19% and over 20%, respectively, but the figures were still 22–103% below the recommended level by the Department of Health. Only 10% of of the breastfeeding women surveyed met the Department of Health’s recommendations for two servings of fruit and three servings of vegetables per day. The study also found that the fat, saturated fat and sugar intakes of more than half of the breastfeeding women were higher than the intake levels recommended by the Department of Health, and about half of respondents had low density lipoprotein cholesterol (“bad” cholesterol) level and body mass index (BMI) that were above the normal values, increasing their risk of developing other diseases in the long run. Breastfeeding women are recommended to pay attention to balanced nutrition during postpartum confinement period. Dr Kenneth LO Ka-hei, Member of RiFood, recommended that postpartum mothers should eat more vegetables and fruit to increase the absorption of different vitamins and minerals, in addition to taking supplements for replenishing protein and iron during the period. Furthermore, poor maternal cardiovascular health in pregnancy may give children a higher chance of developing obesity. Breastfeeding mothers are recommended to consume different types of vegetables and fruit, such as apples, papayas and red grapes, to ensure balanced nutrition.

Prof. HUANG Yonggang of Northwestern University delivers a distinguished lecture on shape programmable 3D mesostructures and functional devices

Prof. HUANG Yonggang, Jan and Marcia Achenbach Professor of Mechanical Engineering, Civil and Environmental Engineering, and Materials Science and Engineering at Northwestern University in the United States, delivered the 28th PAIR Distinguished Lecture titled “Shape Programmable Three-Dimensional Mesostructures and Functional Devices” on 8 August 2024 at PolyU. The lecture attracted more than 100 participants to join in person and captivated an online viewing audience of over 15,500 from different countries and regions to watch the live broadcast on multiple social media platforms, including Bilibili, WeChat, Weibo, YouTube, etc. The lecture commenced with a warm welcome and brief speaker introduction by Prof. CHEN Qingyan, Director of PAIR. During the presentation, Prof. Huang highlighted that many biological systems, such as venue flytraps and nepenthes, exhibit multistable or shape-shifting features. He emphasised the current challenge in the development of morphing structures, pointing out that the complex shape-shifting processes involved in many biological functions are complicated to reproduce by artificial structures. Next, he introduced the assembly approach for achieving multistable 3D mesostructures. The approach proposed by Prof. Huang and his team works similarly to children’s “pop-up” books—it controls the process of substrate compression to deform 2D patterned micro/nano structures into extended 3D layouts. He used videos and images to show how different 2D ribbon patterns can result in different 3D ribbon configurations and reconfigurable structures with diverse geometries. After that, Prof. Huang explained the concepts of shape programming and continuous shape-shifting, and showed some of the research by him and his team to illustrate how 2D precursors can be deformed to various 3D target shapes under external electromagnetic actuation. He also pointed out three significant challenges in achieving shape programme surfaces. At last, Prof. Huang showed examples of how this technology is used to make 3D submillimetre-scale robots and 3D displays. To conclude, he emphasised that the same precursor structure can be deformed to many target shapes by electromagnetic force, and this new tool can bring many novel functions and unique applications. Following the presentation was a lively and insightful question-and-answer session moderated by Prof. Chen. The audience had a fruitful discussion with Prof. Huang. As a token of appreciation for his inspiring talk and support for PAIR, a souvenir was presented to Prof. Huang by Prof. WANG Zuankai, Associate Vice President (Research and Innovation).   Please click here for an online review.
