abstract = "In this work, we have demonstrated a dual fibre Bragg grating (FBG) sensor for a temperature-insensitive chemical concentration or refractive index sensor by etching the cladding of one of the FBGs. The dual FBG sensor was used to measure different solution concentrations of glycerol in water. The sensor showed sensitivities of 2.13×10-3 and 2.28×10-3 at 85% and 0% (pure water) glycerol solution concentrations, respectively. The dual FBG sensors demonstrate that it can be used to detect chemical or biological changes in the surrounding media by measuring the Bragg wavelength and reflectivity differences between the dual FBG's reflection spectrum peaks.",
