Unlocking potential applications in patient care and other key industries: Prof. HUANG Yonggang shares the latest development of bioelastic mechanoreceptors

The diverse array of mechanoreceptors found in human skin provides a versatile engineering interface for transmitting information and eliciting perceptions, with the potential to serve a wide range of applications in patient care and other key industries. However, targeted multisensory engagement of these afferent units continues to present significant challenges, particularly for wearable, programmable systems that must operate adaptively across the body. Prof. HUANG Yonggang, Jan and Marcia Achenbach Professor of Mechanical Engineering, Civil and Environmental Engineering, and Materials Science and Engineering at Northwestern University, United States, and Chairman of International Advisory Committee of PAIR, shared the latest developments in bioelastic mechanoreceptors at the PAIR Seminar, speaking on the topic of “Bioelastic State Recovery for Haptic Sensory Substitution” on 10 September 2025. The seminar attracted over 120 in-person participants and an online audience of more than 16,700 via various social media platforms. To begin his presentation, Prof. Huang described a miniaturised electromechanical structure which, when combined with skin as an elastic, energy-storing element, supports bistable, self-sensing modes of deformation. By targeting specific classes of mechanoreceptors as the basis for distinct, programmed sensory responses, this haptic unit is capable of delivering both dynamic and static stimuli, applied as either normal or shear forces. Next, Prof. Huang went on to discuss a series of systematic experimental and theoretical studies that establish foundational principles and practical criteria for low-energy operation across the natural anatomical variations in the mechanical properties of human skin. A wireless, skin-conformable haptic interface, integrating an array of these bistable transducers, serves as a high-density channel capable of rendering input from smartphone-based 3D scanning and inertial sensors. Demonstrations of this system include sensory substitution designed to enhance the quality of life for patients with visual and proprioceptive impairments. Following the presentation was a lively question-and-answer session moderated by Prof. YAO Haimin, Member of Otto Poon Charitable Foundation Research Institute for Smart Energy and Research Institute for Sustainable Urban Development, and Associate Professor in the Department of Mechanical Engineering.  The audience engaged in a productive discussion with Prof. Huang.  In appreciation of Prof. Huang’s invaluable contributions and insightful knowledge sharing, a commemorative plaque was presented to him by Prof. CHEN Qingyan, Director of PAIR, at the conclusion. Prof. Huang is currently a member of the US National Academy of Engineering, US National Academy of Sciences, a fellow of American Academy of Arts and Sciences, a foreign member of the Royal Society (London), Chinese Academy of Sciences, and 5 other academies in Europe and Canada.   Please click here for an online review.

Prof. WANG Zuankai develops acid-resistant artificial mucus for improving gastric wound healing in animals

A team of researchers and clinicians led by Prof. WANG Zuankai, Associate Vice President (Research and Innovation), Dean of Graduate School, Kuok Group Professor in Nature-Inspired Engineering, Chair Professor in Department of Mechanical Engineering, and Member of Research Institute for Intelligent Wearable Systems (RI-IWEAR) and Research Institute for Sports Science and Technology (RISports), has developed an acid-resistant hydrogel known as “ultrastable mucus-inspired hydrogel” (UMIH). This research has recently been published in Cell Press journal Cell Reports Physical Science. In laboratory tests under acidic conditions (pH2), UMIH demonstrated adhesive abilities 15 times stronger than aluminium phosphate gel (APG), a clinically approved mucosal protectant and antacid used in the management of gastric ulcers and acid reflux. While APG degraded completely after three days, UMIH retained 50% of its structural integrity after seven days in acidic conditions. UMIH was not associated with any toxicity issues in laboratory-grown gastrointestinal cells. It also inhibited the growth of E. coli and S. aureus bacteria, indicating its antimicrobial potential. In pig and rat models of oesophageal injury, UMIH adhered firmly to wounds and improved healing compared to control animals and those treated with APG. UMIH was associated with reduced tissue damage and inflammation, and it promoted the growth of new blood vessels, which is essential for healing. This research was supported by funding from the Innovation and Technology Commission of the Hong Kong Special Administrative Region Government, the National Natural Science Foundation of China, the Science and Technology Planning Project of Guangdong Province, the Science, Technology and Innovation Commission of Shenzhen, and the Shenzhen Medical Research Fund.   Online coverage: Medical Xpress - https://polyu.me/4g4ZI6A EurekAlert - https://polyu.me/4gbGcWj Mirage News - https://polyu.me/4gcqzOf

PolyU Research Boosts Garment Fit and Performance for Sports and Medical Apparel with Ground-breaking Anthropometric Method to Precisely Measure Tissue Deformation

Prof. Joanne Yip, Management Committee Member of the Research Institute for Future Food (RiFood), Member of the Photonics Research Institute (PRI), the Research Institute for Sports Science and Technology (RISports), and the Research Centre of Textiles for Future Fashion (RCTFF), as well as Associate Dean and Professor in the School of Fashion and Textiles, and her research team have developed an innovative anthropometric method to improve the accuracy of measurements for compression-based garments. This method utilises advanced image recognition algorithms to systematically assess soft tissue deformation, significantly reducing errors caused by movement. The team also created an analytical model, based on elastic theory and the Boussinesq solution, to predict tissue deformation, thereby addressing a longstanding challenge in sportswear and wearable technology design. Accurate measurement of tissue deformation is crucial for ensuring garment fit, comfort, and physiological benefits such as improved blood circulation and muscle support. The new method, validated against body scanning, demonstrated exceptional precision, with deviations of just 1.15 mm in static and 2.36 mm in dynamic conditions. This provides designers with reliable data for optimising garment pressure and fit. The technology is adaptable to various compression garments, including sportswear and medical wear, and can be tailored by adjusting material and design parameters. It offers practical benefits for the industry, such as integration with CAD/CAM systems, reduced prototyping costs, and support for personalised garment design. The approach also makes advanced measurement techniques accessible to smaller enterprises by reducing reliance on costly motion-capture systems. The research has been published in a paper titled “A novel anthropometric method to accurately evaluate tissue deformation” in the academic journal Frontiers in Bioengineering and Biotechnology. This technological breakthrough underscores PolyU’s excellence in interdisciplinary translational research, integrating its strengths in fashion, biomechanics, materials science, computing, and engineering to solve real-world challenges in compression sportswear and wearable design.   Press release:https://polyu.hk/ZDMfG Online coverage: RTHK - https://polyu.me/4ga6Lev The National Tribune - https://polyu.me/3I3iazR BioSpectrum - https://polyu.me/47ZTJhj Tech Xplore - https://polyu.me/4gaMLIy Textile Value Chain - https://polyu.me/41Ehms2 Fashion Value Chain - https://polyu.me/4gqPg9X Mirage News - https://polyu.me/4m0ZgI7 Oriental Daily News - https://polyu.me/4p0XAB7 Bastille Post - http://polyu.me/3UYDWaX Line Today - https://polyu.me/3I4NOwW Headline for HK - https://polyu.me/4mLDSaY Hong Kong Economic Journal - https://polyu.me/4lVQVoR (subscription required) Ta Kung Pao - https://polyu.me/47oSkkg

PolyU researchers use novel satellite laser ranging technique to reveal accelerated global average sea-level rise

A research team led by Prof. CHEN Jianli, Core Member of Research Institute for Land and Space (RILS) and Chair Professor of Space Geodesy and Earth Sciences, has utilised advanced space geodetic technologies to deliver the first precise 30-year (1993–2022) record of global ocean mass change (also known as barystatic sea level), revealing its dominant role in driving global mean sea-level (GMSL) rise. Their research further indicates that GMSL has been increasing at an average rate of approximately 3.3 mm per year with a notable acceleration observed, highlighting the growing severity of climate change. The research findings have been published in the Proceedings of the National Academy of Sciences, with Dr NIE Yufeng, a Research Assistant Professor in Prof. CHEN’s team being the lead author. GMSL is primarily driven by two factors: the thermal expansion of seawater, as the oceans absorb around 90% of the excess heat in the Earth’s climate system; and the increase in global ocean mass, which is mainly caused by the influx of freshwater from melting land ice. Therefore, long-term monitoring of global ocean mass change is essential for understanding present-day GMSL rise. In the past, scientists have relied on long-term observations from satellite altimetry to monitor sea-level rise. Barystatic sea level records based on satellite gravimetry only became available with the launch of the Gravity Recovery and Climate Experiment in 2002. SLR is a traditional space geodetic technique used to accurately measure the distance between satellites and ground stations via laser ranging. However, fundamental constraints of SLR, such as the limited number of satellites and ground stations, the high altitude of the satellites (which means SLR-derived gravitational changes capture only the longest wavelengths) and the low-degree gravitational measurements, have restricted its direct application in estimating ocean mass change To effectively utilise SLR-derived gravitational fields for accurate estimates of ocean mass change, the research team implemented an innovative forward modelling technique that tackles spatial resolution limitations by incorporating detailed geographic information of ocean-land boundaries. This approach enables long-term monitoring of global ocean mass changes The research revealed that an increased rate of GMSL resulted in a global average sea-level rise of approximately 90 mm between 1993 and 2022, with about 60% of this rise attributable to ocean mass increase. Since around 2005, the rise in GMSL has been primarily driven by the rapid increase in global ocean mass. This overall increase is largely driven by the accelerated melting of land ice, particularly in Greenland. Throughout the entire study period, land ice melt from polar ice sheets and mountain glaciers accounted for over 80% of the total increase in global ocean mass.
