Abstract

By the sterolithography technique and the ferrite plating, we have fabricated a magnetic micro-machine which coated Fe3O4. The sterolithography technique enables to form the spiral-shape resinous templates and the ferrite plating enables to coat Fe3O4 uniformly onto these templates from an aqueous solution. The total machine weight is light because a resin of the template body is almost the same density as water. We have verified that the machines swim freely and wirelessly in water by applying a rotational magnetic field. As the machine coated with Fe3O4 has a biocompatibility, there is a possibility of medical micro-robots which swim in human body for medical operations.
