摘　　要：Graphene oxide(GO)is a 2D coating material used to improve fiber optics sensors’response to relative humidity.Microbottle resonators(MBRs)have garnered more attention as sensing media structures.An MBR with a 190μm diameter was coated with GO.Then,tapered fiber light coupling was used to investigate the relative humidity sensing performance in the range of 35—70%RH at 25℃.The MBR showed a higher Q factor before and after GO coating.The sensitivity of 0.115 dB/%RH was recorded with the 190μm GO-coated MBR sample compared to a sensitivity of 0.022 dB/%RH for the uncoated MBR sample.These results show that the MBR can be used in fiber optic sensing applications for environmental sensing.
