由于磁性微机械是由磁场驱动的，它们不需要电源电缆，不需要电池，也不需要机身上的控制系统。用钨丝（φ 20μm）制作了外径为0.14mm、长度为1.0mm的螺旋型微机械。采用脉冲激光沉积法（PLD）在螺旋机上沉积NdFeB薄膜磁体。在实验中，无线微机器人以0.2-1.6mm/s的速度游动。结果表明，螺旋形结构适合于微型游泳器。
As the magnetic micro-machines are driven by a magnetic field, they require no power supply cables, no batteries, and no controlling systems on the machine body. We fabricated the spiral-type micro-machine (outer diameter; 0.14mm, length; 1.0mm) by a tungsten wire (φ 20μm). NdFeB film magnet was deposited on the spiral-machine by the PLD method. In the experiment, the wireless micro-machine swam at the speed of 0.2–1.6mm/s. This result indicated that the spiral shape was suitable for miniature swimming machine.
