Abstract
A system for omni-orientational wireless energy transfer is described. A transmitter unit has a transmitter resonator with a coil that is configured to be coupled to a power supply to wirelessly transmit power to a receiver unit. A receiver unit has a receiver resonator with a coil coupled to a device load. At least one of the resonators is a non-planar resonator that spans a non-degenerate two-dimensional surface having at least one concave portion.
Claims20
A system for wireless energy transfer comprising:
- a transmitter unit including a first electromagnetic resonator having a first coil configured to wirelessly transmit power through a magnetic flux, wherein the first coil is rigidly shaped to form a first outline of a first surface;
- and
- a receiver unit including a second electromagnetic resonator having a second coil configured to wirelessly receive power through the magnetic flux, wherein the second coil is rigidly shaped to form a second outline of a second surface;
- wherein at least one of the first surface or the second surface is a non-planar surface occupying three spatial dimensions, and wherein the non-planar surface shapes the magnetic flux to wirelessly transfer power when the rigidly shaped first coil and second coil and physically decoupled and freely movable relative to each other.
A unit for use in an omni-orientational wireless energy transfer system to wirelessly transfer power through a shaped magnetic flux, the unit comprising:
- an electromagnetic resonator having a first coil that is rigidly shaped to form a first outline of a non-planar surface occupying three spatial dimensions, wherein a shape of the non-planar surface is configured to transfer a magnetic flux with a rigidly shaped second coil of a second unit having a second electromagnetic resonator, and wherein the non-planar surface shapes the magnetic flux to wirelessly transfer power when the rigidly shaped first coil and second coil are physically decoupled and freely movable relative to each other.
A method for omni-orientational wireless energy transfer, the method comprising:
- providing a first electromagnetic resonator including a first coil configured to wirelessly transmit power through a magnetic flux, wherein the first coil is rigidly shaped to form a first outline of a first surface;
- and
- placing a second electromagnetic resonator at an operating distance from the first electromagnetic resonator, the second electromagnetic resonator including a second coil configured to wirelessly receive power through the magnetic flux, wherein the second coil is rigidly shaped to form a second outline of a second surface;
- wherein at least one of the first surface or the second surface is a non-planar surface occupying three spatial dimensions, and wherein the non-planar surface shapes the magnetic flux to wirelessly transfer power when the rigidly shaped first coil and second coil are physically decoupled and freely movable relative to each other.
