Abstract

This invention discloses a device comprising multiple functional layers formed on substrates, wherein at least one functional layer comprises an electrical energy source. In some embodiments, the present invention includes an insert for incorporation into ophthalmic lenses that has been formed by the stacking of multiple functionalized layers.

Claims

1. An ophthalmic lens that resides in or on an eye comprising:

an electro-active lens component;

an insert comprising a stack of at least three annular-shaped electrically functional layers including at least one thinned silicon layer, wherein at least one of the annular-shaped electrically functional layers comprises an electrical energy source and at least another one of the annular-shaped electrically functional layers comprises an activation component that activates the electro-active lens component; and

a polymeric lens form in which the insert is embedded.

2. The ophthalmic lens of claim 1, wherein:

the electrical energy source comprises at least one electrochemical cell.

3. The ophthalmic lens of claim 2, wherein:

at least one of the annular-shaped electrically functional layers comprises a semiconductor layer with electronic circuitry to control electric current flow from the at least one electrochemical cell.

4. The ophthalmic lens of claim 3, wherein:

the electronic circuitry is electrically connected to the electro-active lens component within the ophthalmic lens.

5. The ophthalmic lens of claim 1, additionally comprising a metallic layer configured to be an antenna.

6. The ophthalmic lens of claim 1, wherein the electrical energy source comprises at least one of a battery, a capacitor and a receiver.

7. The ophthalmic lens of claim 6, wherein the electrical energy source comprises the battery, wherein the battery is a thin film battery.

8. The ophthalmic lens of claim 7, wherein the thin film battery is enclosed in a packaging to prevent ingress of at least one of oxygen and moisture.

9. The ophthalmic lens of claim 8, wherein the stack of at least three annular-shaped electrically functional layers are accessible to electrical communication outside of the packaging.

10. The ophthalmic lens of claim 1, wherein the electrical energy source is a wire battery.

11. The ophthalmic lens of claim 10, wherein the wire battery provides a voltage capacity of at least about 1.5 volts.

12. The ophthalmic lens of claim 1, wherein at least two of the annular-shaped electrically functional layers comprise the electrical energy source and wherein the electrical energy source is a wire battery.

13. The ophthalmic lens of claim 12, wherein the wire battery provides a voltage capacity of at least about 1.5 volts.

14. The ophthalmic lens of claim 10, wherein the wire battery comprises a conductive wire coated with a zinc anode coating, a separator coating and a silver oxide cathode coating.

15. The ophthalmic lens of claim 12, wherein the wire battery comprises a conductive wire coated with a zinc anode coating, a separator coating and a silver oxide cathode coating.

16. The ophthalmic lens of claim 1, wherein another one of the annular-shaped electrically functional layers comprises a power regulation layer.

17. The ophthalmic lens of claim 16, wherein the power regulation layer charges and controls the electrical energy source.

18. The ophthalmic lens of claim 1, wherein at least two of the annular-shaped electrically functional layers partially overlap.

19. The ophthalmic lens of claim 18, wherein the stack of at least three annular-shaped electrically functional layers is configured to reside outside an optic zone of the ophthalmic lens.

20. The ophthalmic lens of claim 18, wherein the stack of at least three annular-shaped electrically functional layers comprises three silicon layers and an epoxy.

21. The ophthalmic lens of claim 20, wherein the stack of at least three annular-shaped electrically functional layers comprises silicon oxide.
