Abstract
A laminate includes multiple paper layers, with at least one induction coil comprising first and second sets of windings. Two or more paper layers include the sets of windings comprising an electrically-conductive material. The sets of windings may be distributed throughout the laminate layers and provide good wireless induction charging performance in a compact space.
Claims20
A laminate for accomplishing wireless power transfer, comprising:
- at least first and second paper layers, the second paper layer being disposed above the first paper layer in the laminate;
- an insulating layer disposed above the second paper layer;
- at least one induction coil comprising an electrically-conductive material, the induction coil further comprising a first set of windings arranged on the first paper layer and a second set of windings arranged on the second paper layer, the first set of windings and the second set of windings being electrically connected in series;
- wherein the first paper layer, the second paper layer, and the insulating layer encapsulate the induction coil within the laminate.
1 more element
A laminated surfacing material for inductively charging electronic devices comprising:
- at least first and second paper layers, the second paper layer being disposed above the first paper layer;
- an induction coil comprising an electrically-conductive material, the induction coil further comprising a first set of windings arranged on the first paper layer and a second set of windings arranged on the second paper layer, the first set of windings and the second set of windings being electrically connected in series and including at least two electrical contact pads exposed to the outside of the laminated surfacing material;
- and
- the laminated surface material including a decorative layer disposed above the first paper layer and the second paper layer, the decorative layer not including an induction coil or any winding thereof.
1 more element
A method of making a laminated surface material, the method comprising:
- providing at least a first paper layer and a second paper layer;
- forming an induction coil comprising an electrically-conductive material, the induction coil further comprising a first set of windings arranged on the first paper layer and a second set of windings arranged on the second paper layer;
- compressing the first paper layer and the second paper layer according to a lamination process, thereby connecting the first set of windings to the second set of windings in series through a via, the via extending from the first paper layer to the second paper layer.
