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

As global warming intensifies, people increasingly suffer from extreme heat. For those working in a high-temperature environment indoors or outdoors, keeping thermally comfortable becomes particularly crucial. A team led by Dr Dahua SHOU, Limin Endowed Young Scholar in Advanced Textiles Technologies and Associate Professor of the School of Fashion and Textiles of The Hong Kong Polytechnic University (PolyU) has developed 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. Maintaining a constant body temperature is one of the most critical requirements for living and working. High-temperature environments elevate energy consumption, leading to increased heat stress, thus exacerbating chronic conditions such as cardiovascular disease, diabetes, mental health issues and asthma, while also increasing the risk of infectious disease transmission. According to the World Health Organisation, globally, there were approximately 489,000 heat-related deaths annually between 2000 and 2019, with 45% occurring in Asia and 36% in Europe. Thermal protective clothing is essential to safeguard individuals in extreme high-temperature environments, such as firefighters who need to be present at fires scenes and construction workers who work outdoors for extended periods. However, traditional gear has been limited by statically fixed thermal resistance, which can lead to overheating and discomfort in moderate conditions, while its heat insulation may not offer sufficient protection in extreme fire events and other high-temperature environments. To address this issue, Dr Shou and his team have developed intelligent soft robotic clothing for automatic temperature adaptation and thermal insulation in hot environments, offering superior personal protection and thermal comfort across a range of temperatures. Their research was inspired by biomimicry in nature, like the adaptive thermal regulation mechanism in pigeons, which is mainly based on structural changes. Pigeons use their feathers to trap a layer of air surrounding their skin to reduce heat loss to the environment. When the temperature drops, they fluff up their feathers to trap a significant amount of still air, thereby increasing thermal resistance and retaining warmth. 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 expansion of soft actuators and thickening 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. Dr Shou said, “Wearing heavy firefighting gear can feel extremely stifling. When firefighters exit a fire scene and remove their gear, they are sometimes drained nearly a pound of sweat from their boots. This has motivated me to develop a novel suit capable of adapting to various environmental temperatures while maintaining excellent breathability. Our soft robotic clothing can seamlessly adapt to different seasons and climates, multiple working and living conditions, and transitions between indoor and outdoor environments to help users experience constant thermal comfort under intense heat.” Looking forward, Dr Shou finds the innovation to 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. Supported by the Innovation and Technology Commission and the Hong Kong Research Institute of Textiles and Apparel, Dr Shou and his team have also 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.   ***END***

PolyU develops versatile fluidic platform for programmable liquid processing

Society relies heavily on diverse fluidic technologies. The ability to precisely capture and release various chemical and biological fluids plays a fundamental role in many fields. A long-standing challenge is to design a platform that enables the switchable capture and release of liquids with precise spatial and temporal control and accurate volumes of the fluid. Recently, researchers at The Polytechnic University of Hong Kong (PolyU) have invented a new method to effectively overcome this challenge. Led by Prof. WANG Liqiu, Otto Poon Charitable Foundation Professor in Smart and Sustainable Energy, Chair Professor of Thermal-Fluid and Energy Engineering, of the PolyU Department of Mechanical Engineering, the research team has developed a unique fluidic processor, “Connected Polyhedral Frames” (CPFs). With CPFs, switching between liquid capture and release becomes reversible, programmable and independent of used polyhedral frames and processed liquids, making the processor a meta-metamaterial. This research has recently been published in Nature Chemical Engineering, with Dr ZHANG Yiyuan, Research Assistant Professor of the Department of Mechanical Engineering, as the first author. Unlike in the highly developed area of solids manipulation, convenient handling of fluids remains a cumbersome task despite the ubiquity of fluids in, for example, the healthcare, pharmaceutical, biological and chemical industries. As fluids interact with tools, they frequently wet and spread on the solids, preventing complete liquid transfer, impairing volumetric accuracy and causing inter-sample cross contamination. To preserve the purity of fluids, disposable plastics such as pipettes and microtubes are widely used, adding to the global problem of plastic waste. Reversible switching between capture and release is the key to CPFs’ capability to precisely process liquids, enabling the liquid in the network to be retained or drained locally, dynamically and reversibly as desired. In the CPFs, frames above the single-rod connection without a pathway for liquid drainage between frames, capture and retain liquids, thus functioning as capturers. While the frames above the double-rod connection imbibe but release liquids, serving as releasers. This is because when the CPFs are lifted from the liquid, a liquid film forms between the double-rod connections, creating channels between frames that facilitate liquid release. Reversible switching between capture and release can be achieved, using available tools, by constructing or breaking the liquid continuity between frames. CPFs offer a versatile platform that enables many unique functions including 3D programmable patterning of liquids, 3D spatiotemporal control of concentrations of multiple materials, packaging of 3D liquid arrays and large-scale manipulation of multiple liquids. It is compatible with a broad range of liquids, including but not limited to aqueous solutions, biofluids, hydrogels, organic solvents, polymer solutions and oils. Therefore, a variety of biomaterials and chemicals can be incorporated into CPFs for various applications. To demonstrate the practical utility of CPFs in controlled multidrug release, Prof. Wang’s team designed a CPF network for the 3D binary liquid patterning of vitamins B2 and B12. The two vitamins, representing two different types of drug molecules, were encapsulated in sodium alginate hydrogel and gellan gum, respectively, and released in aqueous solution. By altering the thickness of the gel membrane, the relative release rates of the two “drugs” can be precisely controlled. Traditional cotton swabs and flocking swabs suffer from severe sample residues during their sample release. CPFs can effectively overcome this challenge because their frame structure renders free liquid-liquid interfaces for high release efficiency. Using the influenza virus as an example, the research team demonstrated the superiority of CPFs as sampling tools with much better release performance. When the virus concentration was low, the CPFs detected the virus, while both the flocking swab and cotton swab failed to do so. The team has also demonstrated the application of CPFs in biomaterial encapsulation. Taking Acetobacterium encapsulation as an example, the CPFs show many advantages over traditional devices, including by facilitating the separation of bacteria and reaction products, simplifying the microbial reaction process and enhancing the utilisation rate of bacteria. It is conceivable that CPF could also be applied to encapsulate other biological materials for efficient production of other valuable products. In addition to medical and microbial applications, Prof. Wang’s team has further demonstrated the practicability of CPFs for air conditioning. They prepared a commercial-scale humidifier prototype, which has a higher water storage capacity and requires less water flow, making them potentially more energy efficient. The CPFs also allow large-scale 3D liquid dispersion to form a larger surface area, making them very useful for gas absorption. An ideal CO2 cycle process is successfully generated with CPFs, which includes carbon capture and storage and CO2 reutilisation. Importantly, each frame in CPFs captures or releases liquids independent of its base materials, structures and handled liquids, being thus an innovative meta-metamaterial that makes the dream of “precisely scooping water with a bamboo basket” come true. The availability of such a fluidic processor sets a new standard for handling liquids with controllability, versatility and high performance, inspires a new field of meta-metamaterials, and facilitates new scientific and technological breakthroughs in various fields.     ***END***

PolyU develops ultra-stable, record high brightness perovskite LEDs with promising applications

Perovskite materials are significant for enhancing the development and performance of light-emitting diodes (LEDs). However, there are certain technological limitations in advancing overall device efficiency, brightness and lifetime, with the operational stability of Perovskite LEDs (PeLEDs) remaining a major challenge. Researchers from The Hong Kong Polytechnic University (PolyU) have made a breakthrough by developing a 3DFAPbI3 perovskite material system that enables high brightness, efficiency and long device lifetime simultaneously. Prof. LI Gang, Sir Sze-yuen Chung Endowed Professor in Renewable Energy, Chair Professor of Energy Conversion Technology of the Department of Electrical and Electronic Engineering of PolyU, together with Postdoctoral Fellow Dr Zhiqi LI, Research Assistant Professor Dr Zhiwei REN, and the rest of the research team, have engineered a novel technology using an alkyl-chain-length-dependent ammonium salt molecule modulation strategy. They elucidated the roles of alkylammonium salts in managing crystal orientation, controlling grain size, suppressing non-radiative recombination, and thereby enhancing device performance. This represents a critical leap towards future applications and commercialisation of efficient and ultra-stable PeLEDs with record brightness. The research team have achieved efficient, ultra-bright, and stable PeLEDs simultaneously, with high  Electroluminescence External Quantum Efficiency of 23.2%, a record radiance of 1,593 W sr−1 m−2 and a much improved record lifetime of 227 h (at a high current density of 100 mA cm−2). This demonstrates the best performance for DC-drive near-infrared PeLEDs at high-brightness and stability levels. Their research “Grain orientation management and recombination suppression for ultra-stable PeLEDs with record brightness”, has been recently published in the energy journal Joule. Prof. Li Gang said, “This strategy suggests that PeLEDs are not only high-efficiency devices in the laboratory but also promising candidates for commercial high-brightness lighting and display applications, competing with commercially available quantum-dot-based and organic LEDs.” The research team revealed that the performance of PeLEDs is strongly affected by the balance among oriented crystallisation, grain size control and suppression of non-radiative recombination. The key to resolving this dilemma lies in adjusting the molecular interaction between the long-chain alkylammonium salts and perovskite nuclei. Alkylammoniums promote oriented crystallization of perovskite film for lighting, while the molecular interaction between alkylammonium and perovskite affects PeLEDs performance. Notably, the team has successfully utilised molecular engineering of long-chain alkylammonium salts to modulate crystallisation kinetics. This breakthrough strategy enables the production of high-efficiency and ultra-brightness near-infrared PeLEDs with ultralong stability, even under large current excitation. In the development of LEDs, PeLEDs possess substantial advantages, including pure colour, a wider display colour gamut range, cost effectiveness and solution processiblity offering greater flexibility in production. The team’s discovery contributes significantly to the advancement of PeLEDs and their technological impact.    ***END***

ZEISS Adopts PolyU's Patented Technology to Develop ZEISS MyoCare Myopia Control Lenses for Children; Professional ophthalmic products feature patented myopia control technology, effectively slowing down myopia progression in nearly 90% of child wearers

The School of Optometry of The Hong Kong Polytechnic University (PolyU) and ZEISS Vision Care (ZEISS) announced their latest collaborative initiative, ZEISS MyoCare Myopia Control Spectacle Lenses (ZEISS MyoCare Lenses). The lenses utilise PolyU's patented Defocus Incorporated Soft Contact (DISC) technology for myopia management. Through this collaboration, the two parties joined forces to drive better control and management of myopia in children globally. This collaboration has enabled ZEISS to adopt PolyU’s patented DISC technology in its specialist optical products, integrating authoritative academic ophthalmic research with cutting-edge ophthalmological technology to provide the public with new effective professional vision care solutions. The ZEISS MyoCare Lenses uses PolyU’s DISC technology, its patented design adds a set of specialised optical microstructures to the general refractive myopia correction optical structure. The two sets of optical structures are arranged alternately on the lens surface. The corrective area projects the image onto the retina, allowing the wearer to see a clear image, while the optical microstructures project another set of images in front of the retina, i.e., the "forward optical defocus" signal, utilising the eye's natural emmetropisation feedback mechanism to guide the eye and slow down the growth of the eyeball axis of myopic patients. The technology is completely non-invasive and has undergone multiple basic experiments and clinical verifications, proven to be safe, effective and without significant side effects. ZEISS MyoCare Lenses also incorporate patented ZEISS C.A.R.E.® technology. It can effectively decelerate the rate of myopia progression by 48% to 63% and diminish axial length increase by 41% to 77%. Furthermore, these lenses provide wearers with clear vision regardless of viewing distance and direction, and are easy to adapt to, with over 95% of child wearers able to adapt to the lenses within three days. A recent 12-month research report shows that nearly 90% of children wearing ZEISS MyoCare Lenses experienced slow annual myopia progression, compared to 51% of children wearing single vision lenses experiencing fast progression. Moreover, ZEISS MyoCare lenses slowed eye growth from that of a myopic eye to approach that of an emmetropic eye by nearly 70%. Mitigating the Risk of Myopia Progression in Children with Parental Myopia Research confirmed that genetic factors, such as having parents with myopia, increases a child's risk of developing myopia. However, a 12-month clinical study has shown that compared to wearing regular single vision lenses, using ZEISS MyoCare Lenses can effectively slow down myopia progression, even for children with myopic parents, who are especially at risk of developing myopia. This indicates that these lenses can help parents with myopia reduce the increased risk of myopia development in their children, essentially breaking the cycle of worsening myopia each generation. Prof. Christopher CHAO, Vice President (Research and Innovation) of PolyU, said, "PolyU has always been committed to promoting technology transfer. The DISC technology for myopia management is an excellent example to demonstrate how academic research can be transformed into effective industry solutions, offering an additional option in the market for those in need. It is a great pleasure to collaborate with ZEISS, a leading optical brand, to jointly strive for excellence in the development of myopia control for the benefit of community." Mr David Ferran, Vice president, Latin America, Iberia & Asia -C, Vision Care Business Group, ZEISS, added, "ZEISS has been working closely with PolyU for many years. Through this collaboration, we will jointly develop more innovative technologies, aiming to bring the best ophthalmological technology into vision correction solutions, collectively addressing the threat posed by myopia and promoting the well-being of children worldwide.” Mr Calvin Kwan, President of The Hong Kong Optometric Association, said: "Myopia is a serious issue among Hong Kong children, and age 6 to 12 years old is the ‘golden period’ for myopia control. Parents should seize the opportunity to provide the best and most effective myopia control measures for their children, safeguarding their eye health and preventing the development of high myopia and other long-term eye health problems.”   ***END***
