After almost 100 test flights, a dedicated team of researchers at the University of Hong Kong (HKU)’s Mechatronic and Robotic Systems Lab came close to their dream invention – a micro air vehicle (MAV) capable of flying at high speed safely.

Seeing the completion of a bridge or civil structure built from scratch gave Cindy Choi Tsz Wing a strong sense of satisfaction. “Some days are tough, but when you stand under a bridge you designed, knowing it’ll serve people for decades, that’s satisfying—that’s what keeps me going.”

The research project “Scalable fabrication of flexible, ultra-flat diamond films” co-led by Professor Zhiqin Chu in the Department of Electrical and Computer Engineering, and Professor Yuan Lin in the Department of Mechanical Engineering, Faculty of Engineering at the University of Hong Kong (HKU), has been selected as one of China’s Top 10 Scientific Advances of 2025. This innovative technology has successfully enabled the large-scale, high-quality preparation of diamond membranes, laying a critical foundation for the development of next-generation electronic and optical devices.

In light of accelerating technological integration worldwide, the Department of Mechanical Engineering under the Faculty of Engineering of The University of Hong Kong (HKU) organised the X-Dimension: Frontiers in Engineering Science Forum on April 12-13. The event aimed to address the engineering science challenges of the new era.

A cross-institutional research team led by Professor Ngai Wong and Dr Zhengwu Liu from the Department of Electrical and Computer Engineering in collaboration with Tsinghua University and the Southern University of Science and Technology, has developed Co-Located Authentication and Processing (CLAP), a revolutionary privacy-preserving system that overcomes the trade-off between security and performance in edge computing devices.

Cells contain a wealth of information about health and disease, but extracting that data reliably from microscope images remains a major challenge. Many important differences between healthy and diseased cells are too subtle to detect visually, while existing artificial intelligence (AI) tools that can identify such patterns often operate as “black boxes”, making their decisions hard to interpret.

A research team co-led by Professor Yang Lu from the Department of Mechanical Engineering and Professor Chengming Li from the Institute for Advanced Materials and Technology at University of Science and Technology Beijing (USTB), has successfully fabricated a free-standing ultrahard diamond wafer with a diameter of up to 5 inches, a thickness of 3 mm, and a Vickers hardness exceeding 200 GPa.

A research team led by Professor Nicholas X. Fang from the Department of Mechanical Engineering at the Faculty of Engineering has identified a fundamental physical principle called duality symmetry that sets new limits, and opens new possibilities, for designing ventilated sound-absorbing materials.

We are delighted to announce the launch of the MSc Student Commons, a state-of-the-art facility designed exclusively for taught postgraduate (TPG) students of the Faculty of Engineering.

Cutting-edge engineering research projects led by Professors in the Faculty of Engineering are exhibited in the Tam Wing Fan Innovation Wing Two. Free Admissions. Welcome to visit!
