The University of Hong Kong (HKU) garnered a total of 12 awards at the Special Edition 2022 Inventions Geneva Evaluation Days. Research teams from Department of Mechanical Engineering received 1 Gold Medal and 1 Silver Medal with their inventions in the event.
As one of the most prestigious innovation exhibitions, the International Exhibition of Inventions of Geneva (IEIG) is a remarkable annual global event which is devoted exclusively to inventions and innovations. This year’s competition was held in a virtual format in March 2022, where over 780 inventions from 25 countries and regions were evaluated by a panel of professional judges from around the world. The results were announced on March 28.
ME’s award-winning inventions in 2022:
Gold Medal
Fast-reconfigurable large-area interference lithography nanopatterning platform
This novel nanolithography technology is capable of reducing the processing time and cost of large-area nanopatterning by more than 10 times when compared with the best electron beam writers. It adopts fast-reconfigurable beam delivery, active phase stabilization, and computer-controlled automation, and enables high-throughput wafer-scale patterning of 1D and 2D nanostructures with feature sizes down to 40 nm. With the high efficiency and low cost in fabrication, the large-area periodic nanostructures patterned by this technology have great potential in the fields of AR displays, meta-optics, biomedical sensing, solar cells, and LEDs. This technology was developed by Dr. Wen-Di Li, Ph.D. student Mr. Zhuofei Gan, and other team members from the Department of Mechanical Engineering.
Silver Medal
Anti-Covid-19 stainless steel
This is the first anti-Covid-19 stainless steel with Cu-rich precipitates permanently present in the SS matrix with a long-term anti-Covid property, which can inactivate SARS-Cov-2 on stainless steel surfaces. This new invention not only help fight against the COVID-19 pandemic but can also replace some of the frequently touched stainless steel products in public areas, such as lift buttons and doorknobs, using existing powder metallurgy technologies for mass production. The invention was developed by Professor Mingxin Huang and Mr Litao Liu from the Department of Mechanical Engineering, Faculty of Engineering, and Dr Alex Wing Hong Chin, Research Assistant Professor and Professor Leo Lit Man Poon of the School of Public Health, Faculty of Medicine, of HKU.
