A novel magnetic field sensor based on a magnetic fluid (MF)-infiltrated phase-shifted fiber Bragg grating (PS-FBG) is proposed and experimentally demonstrated. The PS-FBG is formed by two FBG sections with a micrometer-level gap between them which is filled with microfluidic MF. External magnetic f...
