Abstract

An eye contact device including at least one of a positive terminal including a first material having a standard reduction potential that is less than a standard reduction potential of chlorine; and a negative terminal including a second material having an electrode potential that favors reduction relative to a reduction of water. A method including one of forming a positive terminal of a two terminal device in an eye contact device, the positive terminal including a first material having a standard reduction potential that is less than a standard reduction potential of chlorine; and forming a negative terminal of the two terminal device including a second material having an electrode potential that favors reduction relative to a reduction of water.

Claims

1. An eye contact device comprising at least one of:

a positive terminal comprising a first material having a standard reduction potential that is less than a standard reduction potential of chlorine; and

a negative terminal comprising a second material having an electrode potential that favors reduction relative to a reduction of water.

2. The eye contact device of claim 1, wherein the first material is a metal.

3. The eye contact device of claim 2, wherein the metal is selected from the group consisting of silver, zinc, iron and aluminum.

4. The eye contact device of claim 2, wherein the metal is silver and the second material is silver chloride.

6. The eye contact device of claim 1, wherein the positive terminal and the negative terminal define terminals of a battery.

7. The eye contact device of claim 1, wherein the positive terminal and the negative terminal define terminals of a rectifier.

8. The eye contact device of claim 1, wherein the positive terminal comprises one or more traces coupled thereto.

9. The eye contact device of claim 1, wherein the negative terminal comprises one or more traces coupled thereto.

10. The eye contact device of claim 1, wherein each of the positive terminal and the negative terminal comprise a combination of silver and silver chloride.

5. The eye contact device of claim 5, wherein the negative terminal further comprises silver.

11. A method comprising one of:

forming a positive terminal of a two terminal device in an eye contact device, the positive terminal comprising a first material having a standard reduction potential that is less than a standard reduction potential of chlorine; and

forming a negative terminal of the two terminal device comprising a second material having an electrode potential that favors reduction relative to a reduction of water.

12. The method of claim 11, wherein forming the positive terminal comprises forming one or more traces coupled thereto.

13. The method of claim 11, wherein forming the positive terminal comprises forming one or more traces coupled thereto.

14. The method of claim 11, wherein forming the positive terminal and forming the negative terminal comprise printing the first material and the second material.

15. The method of claim 11, wherein the first material is selected from the group consisting of silver, zinc, iron and aluminum.

16. The method of claim 15, wherein the first material comprises silver and the second material comprises silver chloride.

17. The method of claim 11, wherein each of the positive terminal and the negative terminal comprise a combination of the first material and the second material.
