چکیده انگلیسی
This paper presents a detailed study of the characteristics of a polymer-coated fibre Bragg grating (FBG) sensor for relative humidity (RH) detection. The sensing scheme used in this work builds upon previous research and extends the application of FBGs in chemical sensing by employing a moisture sensitive polymer coating to induce a mechanical strain on the device through volume expansion. The swelling of the polymer coating as a result of the moisture absorption changes the Bragg wavelength of the FBG, thus giving a direct indication of the humidity level. Sensors with different coating thicknesses were evaluated through a series of experiments carried out over a range of values of RH and temperature to investigate various sensing characteristics which include the RH and temperature sensitivity, the time response and the hysteresis effect. All the sensors tested show a linear and reproducible response with a small degree of hysteresis.
