Abstract
Magnetic micro-machines are driven by a magnetic field. They require no power-supply cables, no batteries, and no control systems on the body of the machine. We fabricated a magnetic micro-machine with a planar structure. In the experiment, the micro-machine swam at a speed of 0.1 to 3 mm/s and had Reynolds numbers between 10-3 and 1. This result indicates that the shape of this micro-machine is suitable for miniature swimming machines.
