Abstract
Recently, various types of mobile micro-robots have been proposed for medical and industrial applications. Especially in medical applications, a motor system for propulsion cannot easily be used in a micro-robot due to their small size. Therefore, micro-robots are usually actuated by controlling the magnitude and direction of an external magnetic field. However, these method enables micro-robots only to perform simple missions such as moving and drilling.
In this talk, we introduce the new concept of micro-robot propulsion using wireless power transfer technology to transfer propulsion force and electric power simultaneously. By changing the impedance of the coil in the receiver, the induced current can be controlled, and to the force can be maximized. The mechanism of propulsion and rotation using Lorentz force and magnetic force is discussed, and the verification of the system using simulation and measurement will be explained.
