The poor intrinsic flexibility of semiconducting ceramic materials hinders their applications in wearable electronics. Here, we present a high-efficient photosensor with extreme levels of bending and repeatable resilience based on wire-in-tube hetero-structures. The ZnO@TiO2 wire-in-tube photosensor demonstrates an ultra-high external quantum efficiency (2.82×106 %) and photosensitivity (1.27×105) upon UV light illumination at 254 nm, and a stability of 85% at the small curvature radius of 0.5 mm. Moreover, the ZnO@TiO2 photodetector demonstrates extremely stable flexibility over 1000 bending cycles. This specific nanoscale architecture has future potential applications for soft integrated electronics.
