From Hospital-centric to Human-centric: “PERfECT” Wearables for Digital Health

“HKU PERfECT” is the first wearable platform that can simultaneously acquire the following three merits.

1. Highly sensitive: By combing electrochemical technology with microelectronic technology, the highest sensitivity is reached.

2. Smallest and lightest: By using the smallest possible electronic units and marrying emerging stretchable bioelectronic technologies, coin-sized and light (0.5 grams) PERfECT wearables have been used for diagnosis and treatment of various diseases, and rehabilitation.

3. Energy efficient: By using interdisciplinary research strategies spanning analytical chemistry, low-power microelectronics, and low-power wireless communication, PERfECT achieves the highest accuracy with the lowest power consumption, ideal for long-term using.

A Simulation Platform for Shared Mobility Services

This is a large-scale simulation platform for managing and controlling Hong Kong taxis. The simulator platform can be used to simulate the movements and trajectories of taxis for idle cruising, picking up passengers, and delivering passengers on a large-scale transportation network. The simulation platform is calibrated by a real dataset of Hong Kong taxis to ensure that the simulation well approximates the reality. This simulator is jointly developed by the teams of Dr. Jintao Ke at HKU and Prof. Hai Yang at HKUST. The simulation platform will be open for public use in the near future.

Solution-processed Flexible Transparent Electrodes and Reflective Electrodes

Innovation Wing Two, Third exhibition / By Tsang Po Yee Bonnie

Professor Choy’s team invented silver nanowire (NW) based flexible transparent electrodes (FTEs) and silver nanoparticle (NP) electrodes. They both have attractive electrical and optical properties, and low-cost. By intergrating both inventions (that is disposing a layer of nanoparticle on the NW FTEs), it can be used as flexible organic photovoltaics.

Analysis and Visualization of MTR Passenger Behavior During COVID-19

This project aims to study the behaviour of MTR passengers during COVID-19 based on a large set (>325GB) of MTR trip records collected in 2019-2020. An efficient and secure online platform has been built to enable researchers to perform analyses and generate visualizations.

3D Printed Anti-counterfeiting Labels At the Microscale

Counterfeiting threatens the global economy and security. According the report issued by the United States Patent and Trademark Office (USPTO) in 2020 “the value of global counterfeiting and pirated products is estimated US $ 4.5 trillion a year.” Despite enormous efforts, conventional anti-counterfeiting approaches such as QR codes can be easily fabricated due to limited data encryption capacity on a 2D in-plane space.

How can we increase the encryption density in a limited space?

Membrane Technology for Clean Water and Energy

Innovation Wing Two, Third exhibition / By Tsang Po Yee Bonnie

Clean water and energy are vital for human activity and socio-economic development. This project focuses on developing more effective reverse osmosis (RO) and nanofiltration (NF) membranes and processes. Professor Tang’s team has pioneered the development of nano-foaming theory and interlayer structure to regulate membranes with excellent performance.

Development and Evaluation of an Immersive Virtual Reality-based Exercise System for Upper Limb Motor Exercises in Patients after Stroke: A Proof-of-concept Randomized Controlled Trial

Innovation Wing Two, Third exhibition / By Tsang Po Yee Bonnie

An immersive virtual reality-based exercise system was developed to support poststroke upper limb exercises. In a 2-week randomized controlled trial, fifty patients used the system for exercises (intervention) or a sham entertainment program (control). The findings demonstrate that the system can improve shoulder joint motion and is safe and acceptable.

Artificial Intelligence for Structural Simulation and Health Monitoring

Innovation Wing Two, Third exhibition / By Tsang Po Yee Bonnie

To address challenges and future developments in structural engineering, Dr. Wang has developed a deep-learning-based platform, which contains (1) physics-informed neural networks (EPINN) for structural simulation and (2) state-of-the-art neural operator (VINO) for structural health monitoring.

Low-Cost and Efficient Green Device for CO2 Recycling and Energy Storage

Fourth Exhibition, Innovation Wing Two / By Yanny Chan

The spread of pathogenic microorganisms in public spaces poses a great threat to human health.

Professor Leung’s team develops a system using far ultraviolet C (UVC) light (wavelength: 222nm) for surface and air disinfection in an actual environment without affecting the normal usage of the area.
Many studies indicated that Far UVC will not create harmful effect on testing creatures such as mice. To further strengthen the safety use of the device for disinfection, the system will not irradiate far UVC light in the presence of people in the area so it will be totally safe in using it.

DipµChip – An Automated Tool for Point-of-care Disease diagnostics

Innovation Wing Two, Third exhibition / By Tsang Po Yee Bonnie

DipµChip is an automated capillary microfluidic-based point-of-care (POC) microsystem allowing rapid and portable detection of various high-impact and mortality diseases, such as pneumonia, sepsis, malaria, and COVID-19. Our Mission is “Empowering access to adequate clinical care for high-impact disease patients using molecular biology and point-of-care microfluidics.” End-users of DipµChip include clinics, hospitals, homes, and assisted living healthcare facilities, democratizing access to adequate clinical care, and saving precious lives of patients in need.
