Schematics of the structures and working principles of the smart flexible electronics‐integrated wound dressing. a) The integrated system consists of a polydimethylsiloxane‐encapsulated flexible electronic layer and an UV‐responsive antibacterial hydrogel. The flexible electronic device is integrated with a sensor for monitoring temperature and four UV‐LEDs for emitting UV light (365 nm) to trigger the release of antibiotic from the UV‐responsive antibacterial hydrogel when needed; a Bluetooth chip is also integrated for wireless data transmission in real time. b) Conceptual view of the integrated system for infected‐wound monitoring and on‐demand treatment: i) real‐time monitoring of wound temperature and providing an alert of hyperthermia caused by infection; ii) turning on UV‐LEDs to trigger the release of antibiotics; iii) infection inhibition by the released antibiotics, resulting in decreased wound temperature.
