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 field to induce current during wireless power transfer, to samsung galaxy tab s7 fe 12.4 in. bundle, 64gb black generate a Lorentz force.To prevent net cancelation of the Lorentz force in the load coil, ferrite films cobra mens fly xl were applied to one side of 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.
