Polymers are supplanting silicon and glass for use in microelectromechanical systems (MEMS), microfluidic lab-on-a-chip (LOC) and micro total analysis systems (µTAS) for reasons of low cost, optical transparency, and biocompatibility. However, difficulties in including active materials for on-chip actuation have limited the commerical success of polymer-based systems. Magnetic actuation employing rare hard earth magnets is capable of high power, large displacement and bi-directional actuation. Over the last decade, there has been much interest among the microsystems industries to fabricate rare earth hard micromagnets for microscale devices. Rare earth micromagnets are attractive for many new and disruptive commercial microdevices in MEMS, RF-MEMS telecommunications, BioMEMS and µTAS. However, the main obstacle to their widespread use has been difficulties with compatibility of permanent magnetic materials with microsystems, especially polymer based systems.

由于低成本、光学透明性和生物兼容性的原因，聚合物正在取代硅和玻璃用于微型机电系统(MEMS)、微流控芯片实验室(LOC)和微型全分析系统(µTAS)。然而，在芯片驱动中加入活性材料的困难限制了基于聚合物的系统的商业成功。采用稀土磁体的磁致动具有功率大、位移大、双向驱动等特点。在过去的十年里，微系统行业对制造用于微型器件的稀土硬质微磁体产生了极大的兴趣。稀土微磁体在MEMS、RF-MEMS电信、生物MEMS和微电子机械系统中的许多新的和颠覆性的商业微器件中具有吸引力。然而，它们广泛应用的主要障碍一直是永磁材料与微系统，特别是基于聚合物的系统的兼容性问题。
