Generating propulsion force in micro-robot using wireless power transfer system

Abstract

In this paper, a micro-robot capable of receiving both electrical energy and mechanical energy is proposed. The electrical energy is transferred using wireless power transfer system, and the mechanical energy is represented as propulsion force. To generate Lorentz force which is the source of propulsion force, the phase difference between source current and load current are controlled by changing capacitance to avoid LC resonance. These proposed concepts are explained with theoretical analysis and validated by simulation results.
