Harvesting EM Energy to Produce Electrical power

The desire to transfer power wirelessly is not a new phenomenon in today’s world. The idea has been driven by the need to diversify the traditional methods of using wires to transfer energy from one point to another. Wireless power transfer also plays a very important role in such a way that electronic devices such as cell phones and laptops could be charged wirelessly. The advancement in technology, the influx of electronic devices and the cost of cables is an alarm to influence the work on wireless power transfer. Wireless power transfer is mostly dependant on the property of magnetic induction. By selecting a specific resonant frequency of an induction circuit, energy can be transferred wirelessly from one circuit to another of the same resonating frequency. The result of this project shows that very little power can be transferred wirelessly using electromagnetic induction. However, improvements can be made to the circuits to obtain better results in the future.
