Abstract

A charge storage fiber is described. In an embodiment, the charge storage fiber includes a flexible electrically conducting fiber, a dielectric coating on the flexible electrically conducting fiber, and a metal coating on the dielectric coating. In an embodiment, the charge storage fiber is attached to a textile-based product.

First claim

What is claimed is:

1. A charge storage fiber comprising:
a flexible electrically conducting fiber, wherein the flexible electrically conducting fiber comprises a flexible insulating fiber;
a first metal (M 1 ) coating on the flexible electrically conducting fiber;
a dielectric (E 1 ) coating on the flexible electrically conducting fiber, wherein the dielectric (E 1 ) coating is on the first metal (M 1 ) coating and surrounds a distal end of the first metal (M 1 ) coating;
a second metal (M 2 ) coating on the dielectric coating, wherein the second metal (M 2 ) coating surrounds a distal end of the dielectric (E 1 ) coating and is electrically isolated from the first metal (M 1 ) coating;
a second dielectric (E 2 ) coating on the second metal (M 2 ) coating and surrounding a proximal end of the second metal (M 2 ) coating; and
a third metal (M 3 ) coating on the second dielectric (E 2 ) coating and surrounding a proximal end of the second dielectric (E 2 ) coating, wherein the third metal (M 3 ) coating is electrically isolated from the second metal (M 2 ) coating.

2. The charge storage fiber of claim 1 , wherein the first metal (M 1 ) coating is longer than the dielectric (E 1 ) coating.

3. The charge storage fiber of claim 2 , wherein the dielectric (E 1 ) coating is longer than the second metal (M 2 ) coating.

4. A charge storage fiber comprising:
a flexible electrically conducting fiber, wherein the flexible electrically conducting fiber comprises a flexible insulating fiber;
a first metal (M 1 ) coating on the flexible insulating fiber;
a dielectric (E 1 ) coating on the first metal (M 1 ) coating;
a metal (M 2 ) coating on and surrounding at least a portion of the dielectric coating;
a second dielectric (E 2 ) coating on the metal (M 2 ) coating; and
a third metal (M 3 ) coating and surrounding at least a portion of the second dielectric (E 2 ) coating.

5. The charge storage fiber of claim 4 , wherein the third metal (M 3 ) coating is in electrical contact with the first metal (M 1 ) coating.

6. The charge storage fiber of claim 4 , wherein the second metal (M 2 ) coating is electrically isolated from the first metal (M 1 ) coating and the third metal (M 3 ) coating.

7. The charge storage fiber of claim 1 , wherein the flexible electrically conducting fiber is a flexible metal wire, wherein the dielectric (E 1 ) coating is on the flexible metal wire.

8. The charge storage fiber of claim 1 , wherein the flexible electrically conducting fiber is a flexible semiconducting wire.

9. The charge storage fiber of claim 8 , further comprising a first metal (M 1 ) coating on the flexible semiconducting wire, wherein the dielectric (E 1 ) coating is on the first metal (M 1 ) coating.

10. The charge storage fiber of claim 1 , wherein the flexible electrically conducting fiber comprises a flexible fiber and a semiconducting coating on the flexible fiber.

11. The charge storage fiber of claim 1 , wherein the charge storage fiber is attached to a textile-based product.

12. The charge storage fiber of claim 11 , wherein the charge storage fiber is woven into a textile-based product.

13. The charge storage fiber of claim 11 , wherein the textile-based product is selected from the group consisting of clothing and a wearable accessory.

14. A charge storage fiber comprising:
a flexible electrically conducting fiber, wherein the flexible electrically conducting fiber comprises a flexible fiber and a semiconducting coating on the flexible fiber;
a first metal (M 1 ) coating on the flexible electrically conducting fiber, wherein the first metal (M 1 ) coating is on the semiconducting coating;
a dielectric (E 1 ) coating on the flexible electrically conducting fiber, wherein the dielectric (E 1 ) coating is on the first metal (M 1 ) coating and surrounds a distal end of the first metal (M 1 ) coating;
a second metal (M 2 ) coating on the dielectric coating, wherein the second metal (M 2 ) coating surrounds a distal end of the dielectric (E 1 ) coating and is electrically isolated from the first metal (M 1 ) coating;
a second dielectric (E 2 ) coating on the second metal (M 2 ) coating and surrounding a proximal end of the second metal (M 2 ) coating; and
a third metal (M 3 ) coating on the second dielectric (E 2 ) coating and surrounding a proximal end of the second dielectric (E 2 ) coating, wherein the third metal (M 3 ) coating is electrically isolated from the second metal (M 2 ) coating.
