▎ 摘　　要

NOVELTY - Method for preparing a flexible UV detection and protection device, involves depositing conductive nanoparticles on a film substrate containing an azobenzene liquid crystal elastomer. USE - The method is useful for preparing a flexible UV detection and protection device in a microcontroller, and a real-time digital display UV light intensity sensor, artificial intelligence field (all claimed), and wearable flexible UV detection device. ADVANTAGE - The device prepares full flexible sensor with liquid crystal polymer as induction component/substrate integration.
