Abstract
A chemical gas sensor based on fiber bragg grating is presented. This invention mainly uses a chemical sensing material, poly-aniline, to apply to the surface of fiber bragg grating. Then a chemical sensing film is formed to detect the concentration and temperature of a volatile gas. Using the carrier of high-pressure hydrogen loading in the light-sensing fiber, the super structure fiber bragg grating is made by use of a phase mask method, and the liquid of hydrofluoric acid is applied to etch the shell of fiber until the diameter is about 15um, then the poly-aniline is grown on the surface of fiber bragg grating to make a film of poly-aniline, so that the necessary peripherals and the size of the sensing terminal are effectively decreased to avoid the influence of fog and the intensity of visible light. Therefore, three goals of simplified sensing complexity, promoted sensing precision, and decreased the cost of sensors are achieved.
