Magnetic Swimming Mechanism in a Viscous Liquid

摘要

A new type of micro swimming mechanism is examined for the development of medical microrobots working in human blood vessels. The magnetic micro swimming mechanism without the wire for supplying the energy is driven by the alternating magnetic field. The magnetic swimming mechanism is examined in a transparent polyvinylchloride pipe filled with a viscous liquid. The test fluid used in the experiment is glycerin. The Helmholtz coil and a bipolar power supply are used to apply the alternating magnetic field in the experiment. Locomotive characteristics of the swimming mechanism in a viscous liquid are analyzed by a high-speed video camera system. The dynamic behavior of a micro swimming robot in a viscous liquid is revealed.
