For chronic wounds, frequent replacement of bandages not only increases the likelihood secondary damage and risk cross infection but also wastes medication. Therefore, in situ real-time monitoring concentrations residual drugs is crucial. Here, we propose a novel strategy that combines triboelectric nanogenerator (TENG) with medical to develop smart bandage based on zeolite imidazolate framework TENG. During process wound healing, electrical output TENG changes continuous release drugs. Based correlation between signal drug concentration, concentration can be monitored situ, guiding staff replace at most appropriate time.
