摘要：
This paper demonstrates multilayer Molybdenum disulfide (MoS2) coated etched Fiber Bragg Grating (eFBG) as highly sensitive hydrophone. Multilayer coating of MoS2 on eFBG is achieved using sputtering of Molybdenum (Mo) followed by sulfurization at 450 degrees C in an inert gas atmosphere. MoS2 coated eFBG subjected to underwater acoustic pressure showed an increase in pressure sensitivity of nearly 20 times at 231Hz in comparison with bare FBG sensors.
