摘　　要：多孔铁芯有利于满足微型磁通门传感器降低功耗的要求,但不同的拓扑结构所取得的效果不同,对多孔铁芯结构进行了拓扑分析与针对性优化,并采用微机电系统(MEMS)工艺制备了不同铁芯结构的微型磁通门进行性能测试与对比验证。实验结果证明:优化后的铁芯结构能更好地降低微型磁通门传感器功耗,提高器件整体性能。Porous core is conducive to meet the requirement of micro fluxgate sensor to reduce power consumption. But different topological structures have different effect. Topology analysis and targeted optimization of porous core are completed. The micro fluxgate based on different porous core structure are fabricated by MEMS technology. Performance testing and comparing experiment are carried out. Result shows that optimized structure of core can better reduce the power consumption of micro fluxgate sensor and improve its overall performance.
