There is a new way to deploy the right microrobotic swarm into a bodily fluid to fight illness. A research group of the Faculty of Engineering has categorised magnetic swarming microrobots and devised ways to select the one that navigates best in a bio-fluid, taking treatment into the vascular system and other confined regions of the body.

The HK$5m Croucher Innovation Award to Engineer Professor Renjie Zhou’s programme brings closer a breakthrough in in vivo imaging technology which takes away the radiation risk from X rays in detecting eye diseases. His work on TPM aims for frequent scanning to catch eye degeneration early and monitor longer term disease.

10,000 times faster, 98% cheaper and better quality, a revolution in nanoscale 3D printing technology comes from the Faculty of Engineering Professor Shih Chi Chen and his team with FP-TPL. It prints layer-by-layer not point-by-point, greatly improves resolution, and heralds a new era for biomedical and nanotechnology.

Hackers roaming the web hijacking clicks for fraud and malware downloads may soon be foiled. Professor Wei Meng of Faculty of Engineering’s browser-based analysis framework has found three techniques used for intercepting user’s clicks. The source code of the framework will be released so web browsers can detect interceptions and warn users.

Phantom Dancer, CUHK student robotics team, won the ABU Robocon championship in Mongolia with some smart moves. After a year of hard work, two robots were engineered to take tricky steps over terrain and on ropes to win this international trophy - a first for CUHK and Hong Kong.
