| Description | Journal: Nanotechnology We report a novel strain sensor based on Reduced Graphene Oxide (rGO) with Palladium (Pd) nano-composite. The sensor was fabricated on the SS304 stainless-steel substrate using a screen-printing method. Graphene oxide was synthesized using modified Hummer's method and reduced using a chemical route. Field Emission- Scanning Electron Microscope (FE-SEM), X-ray diffraction (XRD) and Raman Spectroscopy were used to characterize as-synthesized nano-composite. The as-fabricated strain sensor was tested for tensile strain using Micro- Universal Test Machine (UTM) and the change in resistance for different strains was recorded. The sensor response was observed to be stable and linear within the applied strain range of 0 to 3000 microstrains, and an average gauge factor of 42.69 was obtained in this range. |
