Abstract

A kind of magnetic field sensor with enhanced sensitivity was designed by integrating the fiber Bragg gratings (FBGs) with the curved terbium-dysprosium-iron alloy (Terfenol-D) rods. Seven magnetic field sensors with Terfenol-D rods of different curvatures were fabricated and tested. The highest enhancement in magnetic field sensitivity is observed for sensors equipped with Terfenol-D rods having a curvature of 50 m

$^{-{{1}}}$

. In addition, the designed sensor demonstrated directional sensitivity to the magnetic field, which was obtained to be 3.5 pm/° at 10 mT. The utilization of magnetostrictive materials in unconventional shapes (magnetostrictive rods in curved shapes) in this study not only enhances magnetic field sensitivity but also opens up a world of possibilities for future specific applications.

基于弯曲Terfenol-D棒与光纤光栅结合的光纤磁场传感器

将光纤布拉格光栅（fbg）与弯曲的铽-镝-铁合金（Terfenol-D）棒集成在一起，设计了一种提高灵敏度的磁场传感器。用不同曲率的Terfenol-D棒制作了7个磁场传感器并进行了测试。使用曲率为50 m $^{-{{1}}}$的Terfenol-D棒对传感器的磁场灵敏度有最大的提高。此外，所设计的传感器显示了对磁场的定向灵敏度，在10 mT时获得了3.5 pm/°的定向灵敏度。在本研究中，非常规形状的磁致伸缩材料（弯曲形状的磁致伸缩棒）的使用不仅提高了磁场灵敏度，而且为未来的特定应用开辟了可能性。
