PolyU develops new human-safe magnetorheological fibres, leading innovations in smart wearable textiles

The research team fabricated soft magnetic polymer composite fibres – just 57 micrometers in diameter – by uniformly dispersing magnetic powders in a plastic material (a low-density polyethylene matrix). These fibres not only achieve precise control under low-strength magnetic fields but also solve the problem of heavy magnetic powders. Furthermore, they can be spun into yarns and multi-layer fabrics to realise large-area, controllable deformation. This ground-breaking research was awarded HK$62.37 million under the Research Grants Council’s 2024/25 Theme-based Research Scheme, and has been published in the international journal Nature, in the paper titled “Vector-Stimuli-Responsive Magnetorheological Fibrous Materials”. Unlike traditional smart materials that respond to scalar stimuli such as voltage, current or temperature, these in-house-developed magnetorheological textiles offer unique directionally controllable responses, enabling the development of the following three innovative fabric materials: Flexible Smart Gripper: With electric current controlling the fabric stiffness, the gripper can flexibly grasp soft, fragile or irregularly shaped items – such as worms, tofu, blueberries, mung bean cake, potato chips and fusilli – just like human fingers, significantly reducing the risk of damage or deformation during operation. Remote Emulation Haptic Finger Glove: The all-fabric materials can accurately replicate the surface textures and tactile hardness of different objects. Lightweight and comfortable to wear, they are suitable for diverse applications ranging from remote surgical training, stroke rehabilitation training and virtual fitting, addressing the common drawbacks of bulkiness and heaviness in similar haptic gloves available on the market. Active Ventilation and Thermal-Regulation Fabrics: Addressing the moisture and thermal management challenges in textile clothing, these fabrics can intelligently adjust air permeability by driving fibre structure deformation through electronically controlled magnetic fields, thereby significantly enhancing wearer thermal and moisture comfort.

Revolutionising sustainable distributed energy: Prof. WANG Zhonglin’s Distinguished Lecture on TENGs

On 7 January 2026, Prof. WANG Zhonglin, Director of Beijing Institute of Nanoenergy and Nanosystems, Chinese Academy of Sciences, delivered a PAIR Distinguished Lecture titled “Triboelectric nanogenerators (TENG) for sustainable energy and sensing”.  The event drew a full house at the Chiang Chen Studio Theatre, with over 240 in-person participants, and reached an impressive online audience of more than 16,600 across social media platforms. Prof. Wang began by outlining the historical development of triboelectricity and its significant contributions to human civilisation.  He introduced TENGs as innovative devices that convert mechanical energy—such as motion, vibration or pressure—into electrical energy through the triboelectric effect and electrostatic induction.  By combining layers of materials with different electron affinities and then separating them, TENGs generate a voltage difference that drives current through an external circuit.  Their lightweight, flexible design and use of inexpensive materials make them particularly effective at harvesting low-frequency, high-entropy energy—random, low-density mechanical energy that is widely distributed in the environment.  This positions TENGs as vital components in distributed energy systems and self-powered technologies, with applications spanning the Internet of Things, artificial intelligence, environmental monitoring, medical science and security. Delving deeper, Prof. Wang emphasised the unique capability of TENGs to harvest high-entropy energy from everyday sources such as footsteps, wind and water movement.  Unlike traditional electromagnetic generators, which require consistent and high-quality energy input, TENGs excel at capturing dispersed, low-amplitude mechanical motions. This makes them ideal for powering small devices and sensors in environments where energy is otherwise wasted or difficult to capture.  Their versatility is further enhanced by the wide range of materials that can be utilised, allowing TENGs to be tailored for specific applications—from wearable electronics and medical devices to environmental sensors and industrial monitoring.  This adaptability unlocks vast possibilities for TENG technology, enabling integration into diverse fields such as smart textiles, robotics, ocean science, healthcare, and precision agriculture. In conclusion, Prof. Wang highlighted the profound impact of TENGs on both fundamental science and current technologies.  TENGs enable the development of self-powered devices, promote sustainable and green energy harvesting, and offer low-cost, scalable production methods.  Their flexibility and customisability allow seamless integration into clothing, infrastructure, and even medical implants, while their dual role as energy sources and sensors enhances smart infrastructure and remote monitoring systems.  As TENG technology matures, it is expected to drive the emergence of new commercial products across industries, contributing positively to the sustainability and advancement of human society.  Prof. Wang expressed confidence that TENGs will play a crucial role in supporting the sustainable development of humankind. Following the presentation was a lively question-and-answer session moderated by Prof. XU Bingang, Management Committee Member of Research Institute for Intelligent Wearable Systems (RI-IWEAR) and Professor of School of Fashion and Textiles.  Both on-site and online audiences engaged actively in a thoughtful exchange with Prof. Wang.

When physics meets biology: Prof. Yeomans of Oxford unravels how mechanical forces sculpt tissue shape

Prof. Julia M. YEOMANS of the University of Oxford, UK, delivered a PAIR Distinguished Lecture titled “Active Matter meets mechanobiology: Evading the decay to equilibrium” on 18 December 2025.  The event drew over 70 in-person participants and an online audience exceeding 15,500 across various social media platforms. Prof. Yeomans commenced her presentation by introducing the concept of active systems—systems pushed out of thermodynamic equilibrium by energy at the particle level.  This framework is particularly valuable for understanding biological phenomena such as biomechanics and self-assembly, and supports the design of novel micro-engines and internally driven microchannel flows.  These examples underscore the broader principles of non-equilibrium statistical physics. Building on this foundation, Prof. Yeomans explored the physics of active matter and its implications for mechanobiology and developmental biology.  She discussed how active matter provides a new perspective on the organisation and behaviour of living systems, illustrating this with examples including the intricate patterns that emerge in bacterial colonies and the dynamics of dense active nematics, such as microtubules propelled by motor proteins.  In these systems, far-field flow patterns exhibit nematic symmetry—where liquid crystal molecules align in the same general direction.  Gradients in the magnitude or direction of nematic order—essentially, misalignments of molecules across a surface—create regions with different alignment directions, making them susceptible to splay distortions that lead to bending or curving deformations in tissues.  Notably, active turbulence within these systems can be suppressed by confinement, and in deformable nematic systems, the force axis is not necessarily aligned with the shape axis—adding to the complexity of their behaviour. Prof. Yeomans also addressed the relevance of these principles to medical science, specifically the distribution of lesions in invasive breast cancer.  By comparing histological slides with computational simulations, she presented evidence suggesting that cluster motility, rather than cell proliferation, is the primary driver of the distinctive patterns seen in malignant breast cancer.  This insight has significant implications for understanding tumour progression and could inform future therapeutic strategies. Furthermore, she examined the dynamics of epithelial cells, which can be modelled as deformable active nematics.  In addressing such systems, it is essential to develop theoretical approaches that decouple cellular shape from mechanical stress to provide a more accurate representation of tissue behaviour and development. In conclusion, Prof. Yeomans emphasised the importance of interdisciplinary research at the intersection of physics, biology and engineering, noting that advances in the study of active matter are continually reshaping our understanding of living systems and their complex behaviours. Following the presentation was a lively question-and-answer session moderated by Prof. WANG Liqiu, Member of Research Institute for Sports Science and Technology and Research Centre of Textiles for Future Fashion, Otto Poon Charitable Foundation Professor in Smart and Sustainable Energy and Chair Professor of Thermal-Fluid and Energy Engineering in the Department of Mechanical Engineering.  Prof. Yeomans led a productive discussion that engaged both the on-site and online audiences.
