L Hui, ZHI Fu-biao. Topology analysis and optimization of iron core structure based on micro fluxgate[J]. 2017, 36(10): 14-16+19. DOI: 10.13873/J.1000-9787(2017)10-0014-03.
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.
