Abstract

We demonstrate here an ultrafast, miniature, and high-performance fiber-tip Fabry–Perot (F-P) humidity sensor with 300nm-thick graphene oxide (GO) diaphragm suspended onto the end face of a capillary tube with an inner diameter of 50 μm and a cavity length of 100μm. The sensitivity to relative humidity (RH) spanning from 10%RH to 90%RH was examined based on the wavelength shift in the interference spectrum. Due to the intrinsic hydrophilicity of the porous GO membrane, the developed sensor exhibited an average wavelength variation of 0.2nm/%RH, which indicated a relatively broad and readily detectable RH linear measurement range. More prominently, an ultrahigh response time of 60 ms was achieved over other alternative F-P humidity sensors previously reported, to our knowledge.
