A sci-fi adventure film from the 1960s, Fantastic Voyage, features a group of doctors shrinking into microscopic size and venturing into a patient’s brain to repair damages. A CUHK research team has recently brought this surreal fantasy to life by developing biohybrid soft microrobots, which navigates in tiny lumens for health inspections and medical treatments.

Distinguished as safe, powerful and flexible but plagued by a short life, sulphur-based redox flow batteries have been given a boost to their duration by CUHK engineers, ending a long unsolved challenge. They have designed a novel membrane, keeping the battery’s two electrodes apart and reducing the loss of active materials, so ramping up its lifetime, stability, and its usefulness in grid-scale energy storage devices.

Constant academic pursuit by scholars is essential to driving improvements in life and social progress. Scholars and research studies from CUHK have received international and national awards in various disciplines over the past few months, with research excellence widely recognised.

Architects always have an abundance of design ideas, yet in the real world, there are limitations such as workers’ techniques, time and building costs. A professor from CUHK shows how cable-driven robots transform non-standard and artistic designs into precise executions and eventually help realise the endless possibilities for design concepts.

Smart wearable technology is evolving into a new form. Powering a smartwatch through solar power could be one the ways but how could it be sustainable under a lengthy cloudy sunless day? Researchers in CUHK recently found that you can be in control of your watch’s energy and sustain its battery endurance through walking and the swinging of your arms.

You get lost on a mountain and your cell phone battery goes flat. How do you get help? You help yourself by walking, wearing a featherweight biomechanical device which harvests energy from the movement of your body. CUHK Professor Wei Hsin Liao explains how a moving knee can generate electricity.

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.
