Abstract
In this paper, the authors propose applying a magnetic actuator to a capsule endoscope. Capsule-shaped magnetic actuators were fabricated and in vitro tests were examined. The magnetic actuator was composed of a capsule dummy, a permanent magnet inside the capsule, and a spiral structure. The actuator was rotated and propelled wirelessly by applying an external rotational magnetic field. It was demonstrated that the actuator with 1-mm height spiral could move at 5 mm/s. In addition, the torque required to start rotation was measured. The actuator has great potential for wireless operation of the capsule endoscope.
