“…Additionally, the number of electrons in Au grows, resulting in the material's high electrical conductivity, as reported in [48][10] [5]. As a result, electrons exposed to the sensitive material's surface behave as active sites, increasing the material's electrical conductivity [49]. Since a result, EIS humidity has no direct relationship with humidity performance, as the current generation of humidity characteristics is created by ionic conductivity induced by the creation of high hydronium ions, as well as the generation of protons and charges.…”

Reduced graphene oxide (rGO) possesses remnant oxygen functional groups, hydrophilic characteristics, and a large surface area, making it a one-of-a-kind material with unique qualities that are attributed to the reduction of graphene oxide (GO)process.There are numerous ways that can be utilized in the reduction process; however, it has not yet been completely examined which method is the most efficient in terms of reducing the oxygen-containing functional group from the GO. This is owing to the fact that a successful reduction technique has the potential to broaden the scope of rGO's applicability across a wide range of industrial sectors. This study entails an investigationthe effect of humidity performance on different metal materials such as Pt, Au, Ag, and Cu with fixedfingers spacing of 5um on the reduced graphene oxide (rGO) by electrochemical deposition (ECD) from GO aqueous dispersion. A combination of experimental measurements using humidity chamber, Raman spectroscopy, Electrochemical Impedance Spectroscopy, andScanning Electron Microscopyhave revealed the performance of rGO as the humidity sensor.According to the findings, a good humidity performance was displayed in rGO/Pt, as demonstrated by higher sensitivity and greater response towards humidity which is found to be around 10 times higher response than GO in Hummer’s method, as reported in the literature.These characteristics are both facilitated by the higher ionic conductivity of the material.
