PolyU develops seamless urban navigation system

Professor Chen Wu, PolyU’s Associate Director of Research Institute for Artificial Intelligence of Things and Head of Department of Land Surveying and Geo- Informatics, led a research team to develop a Seamless Urban Navigation System. Applying this novel system, the positioning accuracy is within 10 metres for smartphones. To achieve high precision positioning, researchers integrated measurements provided by multiple GNSSs - China’s BeiDou, the US’s GPS, Europe’s Galileo and Russia’s GLONASS.  The system also won a Silver Medal in the Special Edition 2021 Inventions Geneva Evaluation Days - Virtual Event and a Hong Kong Smart City Award (Smart Mobility Category) in 2018.

New far infrared fibre with great potential for functional and healthcare textiles developed

Prof. Lilly Li, a member of Research Institute for Intelligent Wearable Systems and PolyU’s Institute of Textiles and Clothing, has developed a new way of producing fibres that can absorb and emit far-infrared (FIR) radiation more efficiently than conventional methods. The novel technology can be used to produce high-quality, functional apparel and healthcare products. Unlike the traditional method, Prof. Li’s innovative approach is chemical-free. It is more eco-friendly and cost-effective than the traditional one. It works by modifying the structure of the cross-section of man-made fibres from a conventional circular shape to a triangular one, which is significantly better at both FIR absorption and emission.   The innovation has won Prof. Li a Gold Medal and a Special Merit Award (the Best International Invention, National Research Council of Thailand) at the 47th International Exhibition of Inventions of Geneva 2019 and a Gold Award at the 4th China (Shanghai) International Exhibition of Invention and Innovation 2021.    Please click here to view more detail about the report.

Monitoring medical conditions from inside the body with optical fibre microsensors

Professor Tam Hwa-yaw, Associate Director of Photonics Research Institute, Chair Professor of Photonics and Head of PolyU’s Department of Electrical Engineering, has led a research team to develop novel fibre optic microsensors, which can be implanted into people’s bodies to enable more accurate medical surveillance for surgery and treatment. The research team used an advanced plastic material, ZEONEX, to develop the microsensors, while they also added a ‘side hole’ inside the optical fibres to enhance their sensitivity. Named the “Side Hole Polymer Optical Fibre Sensors”, the microsensors are biocompatible, supple and extremely sensitive to very small pressure changes inside human bodies. It can be made as small as a few micrometres and their sensitivity to pressure is 20 times that of traditional optical fibre sensors. Also, as the microsensors are humidity insensitive, shatter-resistant, chemically inert and biocompatible, they can potentially be used for a broader range of medical applications. The “Side Hole Polymer Optical Fibre Sensors” research findings were published in 2021 in US-based The Optical Society’s Optics Letters. Some of the applications jointly developed with other universities have already been granted patents. Please click here to view more detail about the report.

PAIR Director’s research team can accurately simulate SARS-COV-2 transmissions and infections on airliner flights

On 20 January 2022, Wiley, a multinational publishing company, issued the following press release about recent work conducted by Professor Chen’s team. A study published in Indoor Air simulated the transmission of SARS-CoV-2, the virus that causes COVID-19, on a flight from London to Hanoi and on another flight from Singapore to Hangzhou. When simulating the dispersion of droplets of different sizes generated by coughing, talking, and breathing activities in an airline cabin by an infected person, researchers found that SARS-CoV-2 virus contained in such droplets traveled with the cabin air distribution and was inhaled by other passengers. The scientists counted the number of viral copies inhaled by each passenger to determine infection. Their method correctly predicted 84% of the infected/uninfected cases on the first flight. The team also found that wearing masks and reducing conversation frequency between passengers could help to reduce the risk of exposure on the second flight. “We are very pleased to see that our model validated by experimental data can achieve such a high accuracy in predicting COVID-19 transmission in airliner cabins,” said corresponding author Dayi Lai, PhD, Associate Professor and Associate Head of the Department of Architecture, School of Design of Shanghai Jiao Tong University, in China. “Also, it’s important to know that wearing masks makes a significant impact on reducing the transmission.” This study was published in Indoor Air.

Over 100 guests from the Hong Kong Government, PolyU, the industry and the Centre’s research partners attended physically or online and witnessed this new page. Under PAIR’s leadership, RCRE will become the effective platform aligning people of similar interests to work together in the very important interdisciplinary research field of how to make good use of resource engineering to achieve carbon neutrality. “Our campus is working hard on achieving the goal of carbon neutrality before 2050. RCRE fits very well into this arena and its research work will add great value to helping not only PolyU but the whole community to achieve this target that can benefit our society in a meaningful way,” said PolyU’s Vice President (Research and Innovation) Professor Christopher Chao at the inauguration ceremony. Speaking at the same occasion, Professor Jin-Guang Teng, President of PolyU, stated that PolyU now has the largest research team and facilities among all the universities in Hong Kong focusing on resources engineering towards carbon neutrality, and has established a strong track record and recognised reputation in the waste management research community. PolyU will advance further with the establishment of RCRE for the good of the society. Attending the ceremony online, Mr Wong Kam-sing, Secretary for the Environment, commended PolyU for its contribution and efforts to pool its interdisciplinary talents and facilities to advance the development of decarbonisation technologies and related policy study. The ceremony also featured a fruitful scientific exchange by different PolyU and overseas researchers who presented on a kaleidoscope of topics. Poster presentations on current projects conducted by PolyU researchers were also staged and attracted the attention of all the attending guests at the spot.
