Abstract

Techniques for wireless charging are described herein. For example, an apparatus includes a device formed in a loop. The apparatus may also include a receiving coil disposed around an entire length of the loop. Each turn of the wireless power receiving coil follows the entire length of the loop.

Claims

1. An apparatus for wireless charging, comprising:

a battery powered device formed in a loop and comprising a detachable portion that enables the loop to be broken;

a wireless power receiving coil embedded within the battery powered device to charge a battery of the battery powered device and disposed around a length of the loop entirely wherein the length of the loop is variable based on at least one characteristic of the device, wherein a path of each turn of the wireless power receiving coil follows a same path as the loop entirely, wherein the wireless power receiving coil comprises a breakpoint at the detachable portion, and wherein the breakpoint comprises a connector for completing a circuit formed by the wireless power receiving coil; and

a wireless data transmission component configured to broadcast a data signal comprising data indicating a resonance frequency of the wireless power receiving coil based, at least in part, on changes in the length of the loop.

2. The apparatus of claim 1, wherein the device is comprised of at least a portion of expandable material.

3. The apparatus of claim 2, wherein the wireless power receiving coil comprises an expandable portion embedded within the portion of the expandable material of the device.

4. The apparatus of claim 1, wherein the device comprises a first detachable portion, and wherein the wireless power receiving coil comprises a second detachable portion embedded within the detachable portion of the device.

5. The apparatus of claim 1, wherein the device comprises a foldable portion, wherein the wireless power receiving coil comprises a foldable portion embedded within the foldable portion of the device.

6. The apparatus of claim 1, further comprising detachable connectors to unloop the device.

7. The apparatus of claim 6, wherein the detachable connectors comprise conductive connectors that when attached to each other close an electrical circuit of the wireless power receiving coil.

8. A method of forming a device for wireless charging, comprising:

forming a battery powered device having a loop and comprising a detachable portion that enables the loop to be broken, wherein the length of the loop is variable based on at least one characteristic of the device;

embedding a wireless power receiving coil embedded within the battery powered device to charge a battery of the battery powered device and disposed around a length of the loop, wherein a path of each turn of the wireless power receiving coil follows a same path as the loop entirely, wherein the wireless power receiving coil comprises a breakpoint at the detachable portion, and wherein the breakpoint comprises a connector for completing a circuit formed by the wireless power receiving coil; and

embedding a wireless data transmission component within the device configured to broadcast a data signal comprising data indicating a resonance frequency of the wireless power receiving coil based, at least in part, on changes in the length of the loop.

9. The method of claim 8, wherein forming the device comprises forming at least a portion of expandable material.

10. The method of claim 9, wherein forming the wireless power receiving coil comprises forming an expandable portion embedded within the portion of the expandable material of the device.

11. The method of claim 8, wherein forming the device comprises forming a first detachable portion, and wherein forming the wireless power receiving coil comprises forming a second detachable portion embedded within the detachable portion of the device.

12. The method of claim 8, wherein forming the device comprises forming a foldable portion, wherein forming the wireless power receiving coil comprises forming a foldable portion embedded within the foldable portion of the device.

13. The method of claim 8, further comprising forming detachable connectors to unloop the device.

14. The method of claim 13, wherein the detachable connectors comprise conductive connectors that when attached to each other close an electrical circuit of the wireless power receiving coil.

15. A system for wireless charging, comprising:

a wearable computing device formed in a loop and comprising a detachable portion that enables the loop to be broken wherein the length of the loop is variable based on at least one characteristic of the device;

a wireless power receiving coil embedded within the wearable computing device to charge a battery of the wearable computing device and disposed around a length of the loop, wherein a path of each turn of the wireless power receiving coil follows a same path as the loop entirely and wherein the wireless power receiving coil comprises a breakpoint at the detachable portion, wherein the breakpoint comprises a connector for completing a circuit formed by the wireless power receiving coil; and

a wireless data transmission component configured to broadcast a data signal comprising data indicating a resonance frequency of the wireless power receiving unit based, at least in part, on changes in the length of the loop.

16. The system of claim 15, wherein the characteristic comprise one or more of:

at least a first portion of expandable material, wherein the wireless power receiving coil comprises a second expandable portion embedded within the first portion of the expandable material of the device;

a first detachable portion and wherein the wireless power receiving coil comprises a second detachable portion embedded within the detachable portion of the device;

a first foldable portion, wherein the wireless power receiving coil comprises a second foldable portion embedded within the first foldable portion of the device;

or

any combination thereof.

17. The system of claim 15, further comprising detachable connectors to unloop the device.

18. The system of claim 17, wherein the detachable connectors comprise conductive connectors that when attached to each other close an electrical circuit of the wireless power receiving coil.
