A Microwave Metamaterial With Integrated Power Harvesting Functionality

Emerging Technologies

With the use of low-cost supplies shaped and pitched to seize microwave signals, scientists from Duke University's Pratt School of Engineering have developed a power-gathering maneuver with efficacy parallel to that of contemporary solar panels.

A paper published in the journal, Applied Physics Letters in December 2013 reports that the device wirelessly transforms the microwave signal to direct current voltage that has the ability to recharge a mobile phone battery or other minor electronic device.

The scientists claim that it functions in the same manner as solar panels that transform light energy into electrical current. However, this multipurpose energy gatherer can be adjusted to gather the signal from other energy bases, counting satellite signals, sound signals or Wi-Fi signal.

The pathway to the power gatherer remains in its use of metamaterials, contrived constructions which could seize different types of wave energy and adjust them for suitable uses.

Engineering student Allen Hawkes works in collaboration with another graduate named Alexander Katko and main researcher Steven Cummer who is professor of Electrical and Computer Engineering, created an electrical circuit that has the ability to reap microwaves.

With extra alterations, the scientists stated that the power-harvesting metamaterial could possibly be incorporated into a mobile phone, letting the phone to rejuvenate wirelessly when it is not being used. This application can, principally, let those who live in places without immediate accessibility to a traditional power to gather energy from a neighboring mobile phone tower in its place.
