Study on Fiber Optic Sensor for Ethanol Gas Detection

The combination of gas sensitive material and fiber optic sensor to realize human breath test is one of the important ways in breath testing. Therefore, this paper takes use of perovskite doping assisted by ultraviolet irradiation to improve the optical fiber sensitivity as to fabricate a kind of ethanol gas sensor involved by single-mode multimode single-mode fiber optic and to conduct verification, which explores the gas sensitive performance of the combination of fiber optic and new type composite materials. In the condition of ordinary temperature with ultraviolet irradiation, the ethanol gas could be measured accurately and stabled by selecting flower shaped ZnSnO 3 doped with TiO 2 .
