In this paper, an optical fiber sensor is realized with multi-parameter measurement, including magnetic field, temperature and displacement. Then, the implementation of the three-parameter independent measurement was performed. Among of them, one of fiber Bragg gratings (FBG) is coated giant magnetostrictive particle composite (GMPC) to measure the magnetic field, another FBG is used to measure displacement, and a micro-nano fiber structure of single mode fiber (SMF)-tapering seven core fiber (T-MCF-7)-SMF (S-TM7-S) is applied to measure temperature. Further, the GMPC concentration with the best sensitivity and the best seven-core fiber length were finally selected to form the sensing unit for simultaneous detection of the three parameters. The optical fiber sensor has potential applications for measuring magnetic field environments and system temperatures in high-voltage systems, engineering quality monitoring, as well as circuit safety monitoring.
