Abstract

Magnetic micro actuators are characterized by their wireless operation. In this study, 3 types of magnetic micro actuators are fabricated. First, swimming micro actuator is described. The actuator could swim in the silicone oil. Second, on the basis of swimming actuator, a magnetic actuator running in a pig´s liver was fabricated. Third, magnetic actuator for colonoscope navigation was fabricated. A motion test of the actuator was examined in a large intestine of living dog. All actuators indicate good performances and they have great potential for medical applications.
