Summary: In this study, a novel humidity sensor utilizing a bilayer system was presented, which can detect humidity with high sensitivity in a lower humidity range. By adjusting the density of graphene oxide (GO) flakes, the GO and porous anodic alumina (PAA) layers work synergistically to push the lower detection limit to 0.9% RH. When the density of GO flakes exceeds 1 mg ml-1, the sensor exclusively operates under high humidity conditions.
