Abstract

A hybrid high-security document includes a document and one or more independent light-emitting modules disposed on or embedded in the document. Each module comprises an antenna with multiple turns, an electronic circuit, and a light emitter mounted and electrically connected on a substrate separate from the document. The electronic circuit is responsive to electrical power provided from the antenna to control the light emitter to emit light. The electronic circuit can include a memory storing information relevant to the hybrid high-security document or its use. The information can be accessed by external readers providing electromagnetic energy to the hybrid high-security document. The hybrid high-security document can be a hybrid banknote.

Claims

1. A hybrid high-security document, comprising:

a flexible document; and

one or more independent light-emitting modules disposed on or embedded in the flexible document, each module comprising;

an antenna with multiple turns,

an electronic circuit,

a light emitter mounted and electrically connected on a substrate separate from the flexible document, wherein the electronic circuit is responsive to electrical power provided from the antenna to control the light emitter to emit light, wherein the electronic circuit is formed in a micro-transfer printed integrated circuit having a fractured tether, wherein the light emitter is formed in a micro-transfer printed semiconductor having a fractured tether, or wherein the light-emitting module is a micro-transfer printed module having a fractured tether, and

a power converter that converts a signal with a relatively high current and low voltage to a signal with a relatively high voltage and low current,

wherein the electronic circuit is formed in semiconductor that has an area less than fifty thousand square microns.

2. The hybrid high-security document of claim 1, wherein the power converter is a micro-transfer printed power converter having a fractured tether.

3. The hybrid high-security document of claim 1, comprising an acoustic wave filter, a surface acoustic wave filter, or a bulk acoustic wave filter.

4. The hybrid high-security document of claim 3, wherein the acoustic wave filter has a single dominant acoustic resonant filter mode.

5. The hybrid high-security document of claim 3, wherein the acoustic wave filter is a micro-transfer printed acoustic wave filter having a fractured tether.

6. The hybrid high-security document of claim 3, comprising the acoustic wave filter.

7. The hybrid high-security document of claim 3, comprising the surface acoustic wave filter.

8. The hybrid high-security document of claim 3, comprising the bulk acoustic wave filter.

9. The hybrid high-security document of claim 1, comprising a flexible substrate, ribbon, film, or thread incorporated in, laminated to, or woven into the flexible document and wherein the one or more independent light-emitting modules are mounted on, embedded in, or micro-transfer printed onto the flexible substrate, ribbon, film, or thread.

10. The hybrid high-security document of claim 1, wherein the one or more light-emitting modules comprises a plurality of light-emitting modules.

11. The hybrid high-security document of claim 10, wherein the light-emitting modules of the plurality of light-emitting modules are electrically independent and electrically disconnected.

12. The hybrid high-security document of claim 1, wherein the electronic circuit is responsive to power received by the antenna to cause the light emitter to emit light or to send an electromagnetic signal.

13. The hybrid high-security document of claim 1, wherein the antenna is a multi-layer antenna formed in multiple layers.

14. The hybrid high-security document of claim 13, wherein the multi-layer antenna includes an even number of layers.

15. The hybrid high-security document of claim 13, wherein at least a portion of the antenna is located between the electronic circuit and the flexible document.

16. The hybrid high-security document of claim 13, wherein the electronic circuit is between at least a portion of the antenna and the flexible document.

17. The hybrid high-security document of claim 13, wherein the antenna layers are alternately connected near the edge of the antenna and near the center of the antenna.

18. The hybrid high-security document of claim 1, wherein the light emitter emits light through the substrate in a direction opposite to the flexible document.

19. The hybrid high-security document of claim 1, comprising an acoustic wave filter having a single dominant acoustic resonant filter mode.

20. The hybrid high-security document of claim 1, comprising an acoustic wave filter that is a micro-transfer printed acoustic wave filter having a fractured tether.
