Claims46
A wireless electric field power transmission system comprising:
- a transmitter comprising a transmitter antenna, the transmitter antenna comprising at least two conductors defining a volume therebetween;
- and
- at least one receiver, wherein the transmitter antenna transfers power wirelessly via electric field coupling when the at least one receiver is within the volume.
A method for wirelessly transmitting power, the method comprising:
- oscillating a transmitter antenna comprising at least two conductors defining a volume at a transmitter resonant frequency;
- generating an electric field in the volume;
- positioning a receiver antenna comprising two plates in the volume;
- and
- oscillating the receiver antenna at the transmitter resonant frequency.
A method for wirelessly transferring power, the method comprising:
- resonating a transmitter antenna comprising at least two conductors and a transmitter coil at a start-up frequency;
- tuning the transmitter antenna and the transmitter coil to their resonant frequency;
- generating an electric field within a volume defined by the at least two conductors;
- placing a receiver with a receiver antenna comprising two plates in the volume;
- accumulating a potential difference on the two plates;
- resonating the receiver antenna at the resonant frequency;
- and
- gathering power from the receiver antenna.
A transmitter for wirelessly transmitting power, the transmitter comprising:
- an antenna for creating an electric field, the antenna comprising at least two conductors defining a volume therebetween;
- a coil connected to the antenna;
- and
- a resonator connected to the coil for resonating the coil and the antenna at a resonant frequency, the resonator comprising an auto frequency tuning circuit configured to automatically tune the transmitter.
A receiver for receiving wirelessly transmitted power, the receiver comprising:
- an antenna comprising two conductors;
- a coil connected to the antenna;
- a resonator connected to the coil for resonating the coil and the antenna at a resonant frequency, the resonator comprising an auto frequency tuning circuit configured to automatically tune the resonator.
A wireless electric field power transmission system comprising:
- a transmitter comprising a transmitter antenna, the transmitter antenna comprising at least one conductor;
- and
- at least one receiver, wherein the transmitter antenna transfers power wirelessly via electric field coupling when the at least one receiver is coupled to the transmitter.
