Flexible organic phototransistors are fabricated using polylactide (PLA), a polar biomaterial, as the dielectric material. The charge trapping effect induced by the polar groups of the PLA layer leads to a photosensitivity close to ≈10 4 . The excellent performance of this new device design is further demonstrated by incorporating the phototransistors into a sensor array to successfully image a star pattern.
