Description

technical field [0001] The invention relates to the technical field of wireless power supply, in particular to a relay wireless power supply system based on magnetic resonance. Background technique [0002] Modern people have all kinds of electronic products, even if these products are wireless products, they are only signal transmission wireless, that is, wireless'communication, devices, because they still need to use a wire to transmit power from the wall socket to the device or battery In, rather than completely 'wireless', still can't get rid of the shackles of the power cord. The development of a wireless power supply system can free people from these power lines and truly enjoy the joy and convenience of wireless. For some special occasions where it is impossible or inconvenient to use wires for power supply and the maintenance cost of batteries is too high, such as medical implanted devices such as cardiac pacemakers, or sensor networks such as bridge pressure sensor...
