HKU Engineering researchers develop a soft colour-changing system that may lead to revolutionary optical devices
HONG KONG SAR – Media OutReach – 25 September 2023 – Researchers at the University of Hong Kong (HKU) designed an innovative pixalated soft colour-changing system called Morphable Concavity Array (MoCA). (MoCA): a pixelated colour-changing soft system that mimics the colour-changing structure of butterfly wing. Pixelated soft colour-changing systems are malleable structures that, by manipulating light, can change colour. They have applications in a wide range of […]
