Outline of Final Research Achievements

We devised microvalves that can be remotely controlled without electrical wiring but utilizing an alternating magnetic field, and we conducted basic research for its development. A manufacturing process of the microvalves was established and the microvalves were prototyped. Opening/closing drive of the valves by the AC magnetic field was confirmed. The microvalves were actually driven by applying the AC magnetic field. Although further studies are needed in the future, this study confirmed the feasibility of the proposed microvalves that can be remotely controlled without wiring.
