Abstract

A system ( 100 ) for receiving electrical power wirelessly comprises a first ( 101 ) and a second electrode ( 102 ), with sandwiched there between at least one load module ( 103 ) dispersed in a matrix ( 104 ). Wherein at least the matrix ( 104 ) is applied in wet form.

First claim

The invention claimed is:

1. A system for receiving electrical power wirelessly, the system comprising:
a first electrode and a second electrode,
at least one load module in a matrix sandwiched between the first and second electrodes; the first electrode, the load module in the matrix, and the second electrode forming a capacitor stack,

wherein at least the matrix is applied in wet form and wherein the distance between the first and second electrodes in areas where no load module sandwiched between the two electrodes is larger than in areas where a load module is sandwiched therebetween.

2. A system according to claim 1 , wherein the at least one load module comprises a light emitting diode.

3. A system according to claim 1 , wherein one of the first and second electrodes is reflective and the other one of the first and the second electrodes is transparent or optically active.

4. A system according to claim 1 , wherein the matrix is a transparent or translucent polymer matrix.

5. A system according to claim 1 , comprising a connector for connecting the first electrode and the second electrode to a drive circuit.

6. A system according to claim 1 , wherein the system lacks conductive material in the first and second electrodes in areas were no load module is sandwiched between the two electrodes.

7. A system according to claim 1 , the first electrode and the second electrode each comprising one or more conductive strips, wherein the conductive strip(s) of the first electrode are differently oriented than the conductive strip(s) in the second electrode so as to form a patterned structure with at least one overlapping region between first and second electrodes, such that the at least one load module located at the at least one overlapping region of the first and second electrodes.

8. A system according to claim 1 , wherein the at least one load module has a hydrophobic coating on at least one side facing at least one of the first or second electrodes.

9. Use of a system according to claim 1 in a wall-type application, in a sticker-type application or in a free form luminaire product.

10. A method for manufacturing a system for receiving electrical power wirelessly, the method comprising:
providing a first electrode,
applying on the first electrode a matrix in wet form wherein at least one load module is embedded in the matrix thereby providing at least one load module having a hydrophobic coating on at least one side, such that when applying the wet matrix it is repelled from the at least one load modules at at least one side,
applying on the matrix a second electrode,

such that the first electrode, the at least one load module embedded in the matrix, and the second electrode form a capacitor stack.

11. A method according to claim 10 , wherein the matrix is applied through painting, brushing, spraying or rolling.

12. A method according to claim 10 , furthermore comprising, after applying the second electrode, removing conductive material from the first and second electrodes in areas where no load module is sandwiched between the two electrodes.

13. A method according to claim 10 , wherein providing the first electrode comprises applying first conductive strips on a substrate, and wherein applying the second electrode comprises applying second conductive strips which are differently oriented compared to the first conductive strips of the first electrode so as to form a patterned structure with at least one overlapping region between first and second electrodes, applying second conductive strips of the second electrode being such that the at least one load module is positioned at an overlapping region of the first and second conductive strips.
