PolyU research team develops liquid metal microelectrodes for implantable bioelectronics

The interdisciplinary research team led by Prof. ZHENG Zijian, Associate Director of the Research Institute for Intelligent Wearable Systems (RI-IWEAR), Member of the Otto Poon Charitable Foundation Research Institute of Smart Energy (RISE), Chair Professor of Soft Materials and Devices, and Professor in the Department of Applied Biology and Chemical Technology, has developed liquid metal microelectrodes (μLMEs) which are suitable for skin-attachable and implantable electronic devices. The pioneering study “Wafer-patterned, permeable, and stretchable liquid metal microelectrodes for implantable bioelectronics with chronic biocompatibility”, was published in Science Advances. Wearable or implantable bio-electronic technology requires unique properties that are different from conventional electronics. The developed μLMEs are stretchable, soft and permeable, and can therefore be worn or implanted without causing discomfort or harm to the users. The conductive component of the μLMEs was made from eutectic gallium indium (EGaIn), a liquid metal alloy which allows the μLMEs to retain high conductivity under strain.

PolyU-developed smart car defense system showcases at Smart & Secure City Hall

The Smart Defense System for Connected Vehicle and Smartphone Security developed by Prof. Daniel LUO Xiapu, Leading Member of the Research Institute for Artificial Intelligence of Things (RIAIoT) and Professor of the Department of Computing, and his team, is now being showcased at Hong Kong Productivity Council’s newly launched Smart & Secure City Hall. At the launching ceremony on 4 September, Prof. Luo shared that cyberattacks on cars has surged by 225% from 2018 to 2021; as intelligent automobile network gains prevalence in recent years, it provides hackers with an attack surface that is more convenient and hidden. The smart defense system by the team can provide real-time defense with prompt responses, and state-aware detection capable of detecting various attacks.    Online coverage: Southcn.com - https://polyu.me/3P7o4zw (Chinese only) Bauhinia - https://polyu.me/3L7gOm9 (Chinese only) IT Pro - https://polyu.me/45YyckU (Chinese only)

PolyU’s satellite remote sensing research drives Hong Kong’s smart city development

In a local media interview, Prof. Charles WONG, Associate Dean of the Faculty of Construction and Environment (FCE), Management Committee Member of the Research Institute for Land and Space (RILS), and Professor in the Department of Land Surveying and Geo-Informatics (LSGI), and Dr XU Bing, Assistant Professor in the Department of Aeronautical and Aviation Engineering (AAE), shared PolyU’s recent signing of MoU with the Hong Kong Aerospace Technology Group for enhanced collaboration on remote sensing and aerospace research to facilitate smart city development. The conventional optical remote sensing and synthetic aperture radar observation data obtained in the future will be of high-definition, with an image resolution of less than 1 meter. PolyU was also granted the right to name the satellite which will be launched next year, and will be able to operate and use the satellite at that time.   Online coverage (Chinese only): Ming Pao Daily News -https://polyu.me/48476L1 Hong Kong Economic Times -https://polyu.me/3R8KtPM(subscription required) Sing Tao Daily -https://polyu.me/45TS4pt Headline Daily -https://polyu.me/3RatM6m Wen Wei Po -https://polyu.me/3Pzj6xb;https://polyu.me/47XZ4U2 Ta Kung Pao -https://polyu.me/44LF8Ba Hong Kong Commercial Daily -https://polyu.me/483PNdk

Prof. Michael BATTY from University College London delivers distinguished lecture on science of cities

The PAIR Distinguished Lecture delivered by Prof. Michael BATTY, Bartlett Professor of Planning at University College London, was successfully held on 1 September 2023. The lecture was moved completely online given special arrangements under Super Tyhoon Saola. The webinar attracted over 300 participants from more than 30 countries and regions. It was also broadcasted live on multiple social media platforms, including Bilibili and Weibo, and viewed by over 11,000 online audience in total. In the lecture, Prof. Batty began by giving an overview of the development of science of cities in the last 50 years. Drawing on the system approach and complex theory, he shared how urban science involves top-down and bottom-up thinking, and is a systematic, complex and evolving discipline built on knowledge in social physics, economics, transportation and many scientific methods that yield theories. He illustrated this with city morphology examples from the UK and the Greater Bay Areas (GBA) generated by large-scale computer models. He concluded the lecture by speculating on some of the challenges with fractal geometry, size and scaling, networks, and building models in the field and suggesting the way forward for the discipline. A question-and-answer session moderated by Prof. CHEN Qingyan, Director of PolyU Academy for Interdisciplinary Research and Prof. John SHI Wenzhong, Director of Otto Poon Charitable Foundation Smart Cities Research Institute, followed. The audience was inspired to have a fruitful exchange with Prof. Batty. Please click here for an online review.

PAIR and China Resources foster interdisciplinary dialogue at PAIR Salon

The PolyU Academy for Interdisciplinary Research (PAIR) and the China Resources Research Institute of Science and Technology (CRRIST) jointly organised the PAIR SALON (“the Salon”) at Hong Kong Science Park on 31 August 2023. The Salon, themed on “Interdisciplinary Dialogue”, aims to encourage PAIR researchers and industry to collaborate in the forthcoming Research, Academic and Industry Sectors One-plus Scheme (RAISe+ Scheme), a HK$10 billion initiative by the HKSAR government to provide matching funding to at least 100 university research teams with good potential to become start-ups, with an aim of promoting the transfer and commercialisation of R&D outcomes by university research teams. The RAISe+ Scheme will be launched in fall this year, and local designated universities including PolyU will be eligible for application. The Salon started with welcome speeches by Prof. CHEN Qingyan, Director of PAIR, and Mr LI Nan, Vice Dean of China Resource Research Institute of Science and Technology. Next, Mr Kelvin WONG, Director of Knowledge Transfer and Entrepreneurship Office of PolyU introduced the RAISe+ Scheme. It was then followed by presentations by 22 PAIR members, sharing PAIR’s research progress and outcomes in various fields, including textile technology, energy technology, optical communication, civil infrastructure engineering, urban informatics, traditional Chinese medicine, logistics, mental health and medical imaging, etc. Attendees coming from different sectors also exchanged views and ideas with fruitful outcomes. The Salon was concluded with a closing remark by Prof. LI Li, Associate Director of PAIR. Launched in February 2023, the PAIR SALON is an initiative to provide a platform for closer exchange between academia and industry, with a view to encouraging university-industry research collaboration and facilitating knowledge transfer.

RILS scholar finds causes for wild weather swings from drought to flood

A collaborative study by Dr WANG Shuo, Member of the Research Institute for Land and Space (RILS) and Associate Professor of the Department of Land Surveying and Geo-Informatics (LSGI), Miss QING Yamin, PolyU doctoral student, and researchers from the University of Texas and Columbia University, found that wild weather swings from severe drought to heavy rains are becoming more common with climate change, based on analysis on climate data during 1980–2020. The team also discovered the “land-based feedback loops”, which explains how the movement of moisture from humid regions to dry regions increases the chance of downpours after drought. These results can be useful to help increase the accuracy of predictive climate models and help communities to better prepare for swings between drought and flooding.   The study has been published in Communications Earth & Environment https://www.nature.com/articles/s43247-023-00922-2   Online coverage: Yahoo UK - https://polyu.me/45x6Faq
