dc.description.abstractIn summary, MoS2 coated, etched FBG sensors have been used for various applications. Firstly, the strain sensitivity has been studied; a high strain sensitivity of 6.3 pm/μɛ with a linear range of sensing response from 0 to 2500 με has been achieved in these coated sensors, whereas the bare FBG shows strain sensitivity of 1.2 pm/μɛ. Further, the temperature sensitivity of the bare FBG and MoS2 coated etched FBG sensor are found to be 11.57 pm/°C and 95 pm/°C, respectively, indicating almost one order of magnitude enhancement. Finally, when MoS2 coated eFBGs are subjected to an underwater acoustic pressure field, it exhibits a pressure sensitivity of 60 pm/MPa at 231 Hz, whereas bare FBG shows about 3 pm/MPa at this frequency range. The present investigations show that MoS2 coated eFBGs can be a new platform for high sensitivity applications.en_US
