  • 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.
