To advance radiation exposure management in medical settings, transparent and flexible X-ray detectors are required. In this study, a 3×3 X-ray detector array using pentacene thin films and CNT thin-film electrodes was fabricated on a PET substrate, enabling real-time two-dimensional dose imaging. Further evaluations under bending deformation and repeated flexing revealed no significant degradation in sensitivity down to a minimum curvature radius of 3.0 mm and after 4000 flexing cycles, indicating high flexibility and mechanical durability.
