In this paper, we propose a novel coil structure, using a ferromagnetic material which concentrates the magnetic field, as the propulsion system of a wireless power transfer (WPT) based micro-robot.This structure uses an incident magnetic cardboard sweet stand field to induce current during wireless power transfer, to generate a Lorentz force.To prevent net cancelation of the Lorentz force in the load coil, ferrite films were applied to one side of w insta saree the coil segment.

The demonstrated simplicity and effectiveness of the proposed micro-robot showed its suitability for applications.Simulation and experimental results confirmed a velocity of 1.02 mm/s with 6 mW power transfer capacity for the 3 mm sized micro-robot.
