For the fabrication of a wearable flexible ultraviolet photodetector device, Mg-doped ZnO was studied. MgZnO nanorods were grown using the hydrothermal synthesis method, which can grow MgZnO at low temperature on a polyether sulfone (PES) substrate. The MgZnO nanorods showed a crystal structure in which hexagonal MgZnO and cubic MgZnO were mixed as Mg was doped. The MgZnO nanorods doped with 3 at% Mg showed the best crystallinity, and the sheet resistance value was 76 $\Omega/$□. An ultraviolet (UV) photodetector fabricated using the MgZnO nanorods had a maximum current of 1.9 $\mu$A at a 1 V applied voltage in a UV irradiation environment, a rise time of 21 seconds, a decay time of 17 seconds, and an on/off current ratio value of 1.96 $\times$ 10$^2$.
