Microwave signals turned into electrical power

An electrical current capable of charging a mobile phone has been created from microwave signals.

…as efficient as using solar panels.
The device they created used metamaterials…
Using fibreglass and copper conductors on a circuit board, the researchers converted microwaves into 7.3 volts of electricity. A USB charger, which is often used to recharge mobile phone batteries and cameras, provides about five volts.
…hope that the technology can be built in to mobile phones…
…it could help users living in remote areas without access to the power grid.
