Can you imagine how hot you would feel when a heatwave comes if you lived in a tin-sheet house? It would be like living in a steam oven. Heatwaves are roasting the world, smashing records with unrelenting severity. A CUHK research team has developed a high-performance radiative cooling paint based on recycled glass, a forgotten resource in our communities. It can potentially provide buildings with supplemental cooling without consuming energy.
One of the most innovative universities in the city and the region, CUHK is committed to producing impactful research and propelling innovation in Hong Kong and beyond. Recently, CUHK students and scholars have excelled in several national and international competitions, while the CUHK Hong Kong-Shenzhen Innovation and Technology Research Institute (Futian) (FITRI) has recently been unveiled to foster cross-border I&T collaboration.
Venom may be one of Spider-Man’s greatest nemeses, but the alien symbiote who can stretch and deform itself has inspired scientists to create soft robots that could transform numerous aspects of medical care, from targeted drug delivery to minimally invasive surgery. Professor Zhang Li from CUHK decided to channel Venom’s superpowers into building soft robots based on ferrofluids and a new silicone elastomer, which can be deformed in ever more complex ways, making them capable of a growing range of functions within the human body.
What can you do with tape? Seal your package or to bind an injury? The uses of tape go much further than that in the hands of a CUHK Engineering professor who has devoted himself to medical robotics. By simply tattooing magnetised patterns onto tapes and using a magnetic field, a highly versatile “origami” soft robot is miraculously brought into being that can morph into a variety of 3D shapes - and behold, they have a future in medical and industrial applications.
In a flower garden, we have army of honeybees that swarm to defend enemies; in a tortuous human lumen, we have army of microrobots that swarm to carry drugs that attack maladies. CUHK engineering professors have devised an avant-garde AI system that lets these microrobots navigate like bees and change shape inside complex environments like human bodies.
Life in an extremely cold region without electricity for heating and lighting can be a miserable experience, especially as existing battery technologies cannot retain a reliable power supply in such cold weather. When winter storms sweep across cities, the power crisis they cause can leave millions of people without electricity. CUHK researchers are trying to fix that with a new technology that promises to bring stability to electrical storage, even at very low temperatures.
Professor Mei-Po KWAN from CUHK’s Department of Geography and Resource Management has been awarded the James R. Anderson Medal of Honor in Applied Geography, the highest honour in the field, for her multidisciplinary contributions to applied geography; while Professor YU Jun from the Faculty of Medicine has been awarded the Guanghua Engineering Science and Technology Award by the Chinese Academy of Engineering in recognition of her distinguished achievements in gastrointestinal cancer studies.
loT is the key to building a smart city, in which sensors act as eyes and ears of the system to collect and convert physical variables into electronic signals for analysis. A self-powered wireless sensing e-sticker, thin as two human hairs, developed by CUHK, converts the power of a finger touch into electromagnetic wave signals to advance the smart sensing technology. Another discovery is a TENG with high power output to better harvest mechanical and biomechanical motion.
With a clear and pronounced emphasis on promoting “Research and Innovation”, CUHK has been working diligently to bring out talents and pioneers in the industry. Recently, CUHK scholars received global and national recognition for their research excellence, among whom Professor Dennis LO from Medicine has become the first Chinese scientist to receive the Royal Medal in biological sciences.
Driving research, innovation and entrepreneurship initiatives, CUHK recently hosted two major highlighted events, CUHK Innovation Day and CUHK Entrepreneur Day, to provide its communities an exchange platform to showcase innovation and entrepreneurial achievements to industries and the public, as well as translate innovative research into practice.
It is a tough task for an able bodied person to learn the violin, let alone someone without an arm. A multi-functional prosthetic with convertible adaptor developed by CUHK researchers gave hope to Roy who had lost his left arm and took him onto the stage in a concert given by a thousand-player orchestra, where he demonstrated his dream playing wonderful pieces of music.
The ocean is the largest energy treasure house on earth, covering approximately 70% of its surface. Harvesting this is called “blue energy” and it’s a solution to energy crisis. However, given its complex technology and high cost, electricity generation from blue energy isn’t easy. A CUHK research team has recently developed a high-efficacy generator for harnessing ocean wave energy, which turns a new page.
