Wireless Power Transmission System Based on Magnetic Inductive Resonance of Couple Circuit

In this paper, By magnetic inductive resonance method or wireless inductive power transfer method, a couple circuits can be used to transfer power wirelessly, where the individual nodes are battery less to make them maintenance free. The main working principal of magnetic inductive resonance is Electromagnetic field inductance between two coils that are tuned to resonate at the same frequency. This type of method has a high quality Factor (Q) and Consist of air cored to avoid iron losses. For energy harvesting wireless or battery less sensors can be use and possible to store in capacitors. One of the methods of wireless power transmission scheme is microwave power transmission, which can interfere with data transmission, where for data transmission and acquisition can easily possible by magnetic inductive resonance.
