Gold Medal with the Congratulations of Jury

 “Anti-scratch thin film coating on metal surface” by Professor Cheah Kok-wai, Chair Professor of the Department of Physics

The innovation is a thin anti-scratch film coated on a metal surface in a 3D design. It adds value to metal-based products such as watch cases and straps as it increases surface wear resistance without sacrificing their original appearance. Please click here for more details about the research.

Silver Medal

 “Portable body motion analyser for elderly fall risk assessment” by Professor Jeffrey Cheung, Adjunct Professor of the Department of Physics

The analyser is a wearable and compact device that simplifies the gait analysis process with easy access to those gait parameters. The assessment test only takes five minutes. The collected data will then be associated with a user’s fall vulnerability with the help of the cloud and AI. This technology enables an efficient approach to caring for the elderly, who will benefit from the prevention of serious health risks. Please click here for more details about the research.
