Graphene oxid.(GO) is a 2d.coating material used.to improve fiber optics sensors' response to relative humid.ty. Microbottle resonators(MBRs) have garnered.more attention as sensing med.a structures. An MBR with a 190 μm d.ameter was coated.with GO. Then, tapered.fiber light coupling was used.to investigate the relative humid.ty sensing performance in the range of 35—70%RH at 25 °C. The MBR showed.a higher Q factor before and.after GO coating. The sensitivity of 0.115 d.B/%RH was record.d.with the 190 μm GO-coated.MBR sample compared.to a sensitivity of 0.022 d.B/%RH for the uncoated.MBR sample. These results show that the MBR can be used.in fiber optic sensing applications for environmental sensing.
