- The study investigates how impedance changes with humidity levels ranging from 20-90% using a polymer synthesized from varying amounts of graphene oxide (GO) mixed with polyaniline, measured across frequencies from 100 Hz to 5 MHz.
- An electrochemical deposition method was used to create a film on an indium tin oxide glass slide, demonstrating that higher humidity leads to lower impedance values, indicating an inverse relationship between the two.
- The GO-based humidity sensors exhibit a remarkable sensitivity of 75-99%, significantly outperforming traditional platinum capacitive sensors by about ten times, along with quick response and recovery times, making GO a promising material for advanced humidity sensing.
