Portable Balance Scale was invented by Professor Jeffrey Cheung, which measures people's balance index to reduce their risks of falling over. By analysing the body's moving amplitude when it tries to maintain balance on an unstable platform, the specific index value can then be measured. The greater the amplitude, the higher the index; and a high index indicates poor balance capability. The whole measurement process is as simple as stepping on a scale.
The invention won a gold medal in the sports category, as well as the Prize of the Romanian Association of Nonconventional Technologies (special medal) at the 45th International Exhibition of Inventions, Geneva.
