Researchers at City University of Hong Kong have developed an electrostatically charged face mask that can replenish its charge through the wearer’s breathing action. The electrostatic charge helps the mask to adsorb tiny particles, such as SARS-CoV-2 viruses. However, such masks typically lose their charge and ability to bind particles over (Read more...)

Soft Robot Biodegrades Inside Body
Researchers at the City University of Hong Kong have developed a magnetic soft millirobot that can grab and release objects, and move around by rolling. The device can be controlled using magnetic fields, and consists of a biodegradable gelatin and iron oxide microparticles. The technology has significant potential as a minimally invasive drug deli (Read more...)
