摘　　要：磁性液体既具有固体磁性材料的磁性又具有液体固有的流动性。在磁场的作用下,呈现出许多固体磁性材料所没有的特性,从而具有广阔的应用前景。传感器是磁性液体最重要的应用领域之一。利用磁性液体设计的传感器类型更多样、结构更完美、性能更优越。本文分析了磁性液体传感器工作的理论基础,介绍了国内外磁性液体传感器的研究状况。Magnetic liquid has both the magnetic properties as solid magnetic materials and the fluidity inherent to liquid. It shows distinct properties under magnetic field, which make it different from other solid magnetic materials. Magnetic liquid has wide application prospects and one of its important applications is sensor design. The sensor with magnetic liquid is featured by its various types, perfect structure and super performance. In this paper, the theoretical foundation of magnetic liquid sensor is analyzed and the application of magnetic liquid in sensor is investigated.
