WIRELESS ENERGY TRANSFER FOR WEARABLES

摘要

The disclosure features resonators to wirelessly transfer energy to a wireless power device including a device resonator coil having a dimension D. The resonator can include a first plurality of conductor windings wound approximately in a first plane and having first and second conductor leads, and a second plurality of conductor windings wound in a second plane and having third and fourth conductor leads. The first and third conductor leads can be coupled to each other and the second and the fourth conductor leads can be coupled to at least one capacitor. The first plane and second plane can be spaced apart by separation S and substantially parallel. The separation S between the first plane and second plane can be approximately equal to or greater than the dimension D of the device resonator coil.
