Wearable UV photodetectors (PDs) have attracted interest recently for detection of excess exposure of the skin to the UV radiation. Despite numerous advances made in this direction, many challenges remain, particularly in terms of device reliability under extreme mechanical deformations simultaneously and self‐powering, etc. Herein, a self‐powered stretchable PD developed with kirigami‐inspired honeycomb‐patterned zinc oxide (ZnO) nanowires (NWs) and coupled with a triboelectric nanogenerator (TENG) is presented. After studying in detail the influence of ZnO NWs dispersion medium and metal‐ZnO NWs contacts, a novel fabrication approach employing the structural engineering on NWs‐elastomer composite is used to achieve high stretchability. The fabricated ZnO NWs‐based UV PDs, embedded inside kirigami‐inspired honeycomb‐patterned elastomeric substrate, exhibit unprecedented stretchability …
