External power for medical implants

    The idea is to develop a wireless power transmission device that will be able to power implanted medical devices.
    The system will consist of a transmitter that will create a modulating magnetic field and a receiver with a metal band that will move with changes in the field. The movement will be translated into electricity able to power implants within range of the magnetic field, up to about 50 cm.
    The magnetic field will pose no threats to humans, and the power will be sent through any non-magnetic material, including bones, organs, and some metals.
