This paper reports some very first results about the development and the metrological evaluation of a fiber Bragg grating (FBG) ethanol sensor, able to work into liquid solutions. The sensing device is established by dip-coating a single-mode silica FBG with a poly(methyl methacrylate) (PMMA) coating film. The thickness of the sensing coating was set by means of a deposition system able to control the rising/dipping rate of the FBG in the PMMA solution. Tests were performed in a range spanning from 3% to 40% in v/v of ethanol in water in order to investigate the device response. In particular, dynamic performance in terms of response and recovery time values were also estimated.

Abstract
This paper reports some very first results about the development and the metrological evaluation of a fiber Bragg grating (FBG) ethanol sensor, able to work into liquid solutions. The sensing device is established by dip-coating a single-mode silica FBG with a poly(methyl methacrylate) (PMMA) coating film. The thickness of the sensing coating was set by means of a deposition system able to control the rising/dipping rate of the FBG in the PMMA solution. Tests were performed in a range spanning from 3% to 40% in v/v of ethanol in water in order to investigate the device response. In particular, dynamic performance in terms of response and recovery time values were also estimated.Pubblicazioni consigliate
