PolyU received a total of 18 accolades at the 4th Asia Exhibition of Innovations and Inventions Hong Kong (AEII), including the Grand Prize, one Special Prize, seven Gold Medals, eight Silver Medals and one Bronze Medal. The winning entries include a research project from the Centre for Eye and Vision Research (CEVR) in collaboration with the University of Waterloo. AEII is a prestigious annual exhibition and competition dedicated to innovations and inventions in Asia. It brings together scholars, experts, and inventors from around the world to showcase a diverse range of groundbreaking inventions and solutions.

Among these, the project “Highly integrated wireless ultrasonic motor system for fully enclosed environments,” led by Prof. CHAU Kwok-tong, Chair Professor of the Department of Electrical and Electronic Engineering at PolyU, was awarded the Grand Prize and a Gold Medal. The wireless ultrasonic motor system designed by the team features a single integrated magnetic coupler connected to the motor, which can control motor systems in fully enclosed environments without power cables, batteries and controllers. The system is adaptable to various applications, facilitating seamless integration. Its design streamlines operation without additional controllers or sensors, which is ideal for environments where traditional cabling is impractical, such as in robotic arms, enhancing mobility and flexibility. In enclosed environments like underground pipelines or underwater propellers, it avoids complications from perforated installation cables, preventing gas or liquid leaks. This innovation brings new solutions for advanced applications in robotics and industrial automation.
