Abstract
The present application relates to apparatus for wirelessly charging a rechargeable battery, the apparatus comprising: a charging resonator assembly for converting energy from a magnetic field external to the apparatus into an electric current; and a charging circuit for charging the battery using the electric current, wherein the charging resonator assembly includes a plurality of microelectromechanical system (MEMS) switches which, when open, divide the charging resonator into a plurality of electrically unconnected resonator portions, and which, when closed, connect the plurality of resonator portions to form a continuous resonator.
