Abstract

Provided is a wireless recharging set. A source unit including a source resonator may transmit power wirelessly in all directions, and a device may receive the transmitted wireless power regardless of location.

Claims

1. A wireless charging set comprising:

a source unit that is flexible and that comprises at least one source resonator configured to transmit power wirelessly; and

a device that comprises at least one target resonator matched with the wireless power transmitted which is configured to receive the wireless power from the source unit, and to charge a power source using the wireless power received by the at least one target resonator.

2. The wireless charging set of claim 1, wherein the source unit is disposed in a bar in a pillar shape, and the device is located around the bar.

3. The wireless charging set of claim 1, wherein the source unit is disposed in a charging platform of the device.

4. The wireless charging set of claim 1, wherein the source unit is disposed in a bar in a pillar shape and a charging platform of the device.

5. The wireless charging set of claim 1, wherein, when a plurality of devices are to be charged, the plurality of devices are simultaneously charged by the source unit.

6. The wireless charging set of claim 1, wherein the device comprises a plurality of target resonators, and the plurality of target resonators are disposed perpendicular to each other.

7. The wireless charging set of claim 1, the device comprises a plurality of target resonators, and the plurality of target resonators simultaneously receive the wireless power.

8. The wireless charging set of claim 1, wherein the at least one source resonator is a thin film resonator.

9. The wireless charging set of claim 1, wherein the at least one target resonator is wrapped with a film for waterproofing and shielding.

10. The wireless charging set of claim 1, wherein:

the device is three dimensional (3D) eyewear; and

the 3D eyewear includes a first target resonator disposed in a temple of the eyewear, and a second target resonator disposed in a bridge or a frame of the eyewear.

11. A source unit for wirelessly transmitting power to at least one device, the source unit comprising:

an exterior surface;

one or more source resonators that are flexible, that are disposed on the exterior surface, and that are configured to transmit power wirelessly to the at least one device.

12. The source unit of claim 11, wherein the exterior surface comprises a cylindrical shape, and the one or more source resonators are flexibly wrapped around the cylindrical shaped exterior surface.

13. The source unit of claim 11, wherein the exterior surface comprises a platform and a cylindrical shaped bar protruding from the platform, and each of the platform and the cylindrically shaped bar comprises one or more source resonators for wirelessly transmitting power to the at least one device.

14. The source unit of claim 11, wherein the one or more source resonators comprise a plurality of source resonators that are disposed in parallel to each other on the exterior surface.

15. The source unit of claim 11, wherein the one or more source resonators are configured to transmit power wirelessly in an omni-directional fashion.

16. The source unit of claim 11, wherein the one or more source resonators are configured to simultaneously transmit power wirelessly to a plurality of devices.

17. A device for receiving power wirelessly from a source unit that comprises one or more flexible source resonators attached to an exterior surface of the source unit, the device comprising:

a target resonator configured to receive power wirelessly from the one or more flexible source resonators of the source unit; and

a target unit configured to transfer the received power to drive the operation of the device.

18. The device of claim 17, further comprising a matching control configured to set an impedance matching frequency of the target resonator to perform impedance matching with the one or more flexible source resonators and the target resonator.
