The exploration of optical properties in mechano-optical conversions holds promising prospects for diverse technological applications. Here, we introduced the design of MQ particles (MQPs) and the development of a wearable and rewritable photonic film as a communication toolbox for dark conditions with communication limitations or underwater environments. The films demonstrated a quenching along handwritten trajectories under mechanical pressure, and the written content can be easily erased with short ultraviolet (UV) light irradiation. The high reproducibility of MQ and ML responses was observed in the films, and we revealed the underlying mechanism between these two phenomena. Moreover, the photonic films exhibited remarkable resistance to humidity and retained their rewritable property underwater for extended periods. We further demonstrated the rewritable property of films on a human hand, confirming their effectiveness as a wearable photonic skin for communication underwater.
