Skin wounds are commonly seen, while their repair can be severely affected due to bacterial infections. Using the wearable triboelectric nanogenerators (TENGs) as miniaturized electrical stimulation (ES) devices at the wound site is an appealing strategy for infected skin wounds repair. However, the development of an integrated TENG patch to achieve in situ ES as well as controlled drug loading/release remains challenging. Herein, a flexible TENG patch is rationally designed with a surface-engineered electrode possessing Mg-Al layered double hydroxide as a smart drug container and friction lay...
