Abstract

Disclosed is a fibrous triboelectric generator. The fibrous triboelectric includes a first textile; a first electrode layer that is formed on a surface of the first textile; a friction layer that is formed on a surface of the first electrode layer and is able to be electrically charged by friction; and a second electrode layer that is able to undergo friction with the friction layer.

First claim

What is claimed is:

1 . A fibrous triboelectric generator comprising:
a first textile; a first electrode layer that is formed on a surface of the first textile; a friction layer that is formed on a surface of the first electrode layer and is able to be electrically charged by friction; and a second electrode layer that is able to undergo friction with the friction layer.

2 . The fibrous triboelectric generator of claim 1 , wherein the friction layer consists of a nonconductive polymer and includes a surface with a concavo-convex structure.

3 . The fibrous triboelectric generator of claim 2 , wherein the surface of the friction layer includes:
a plurality of first linear protrusions that are extended along a first direction; and a plurality of second linear protrusions that are extended along a second direction which is different from the first direction.

4 . The fibrous triboelectric generator of claim 2 , wherein the surface of the friction layer includes a plurality of protrusions that are spaced apart from one another.

5 . The fibrous triboelectric generator of claim 1 , wherein the friction layer includes:
a metal oxide that protrudes from a surface of the first electrode layer; and a coating layer that coats a surface of the metal oxide and the surface of the above first electrode layer.

6 . The fibrous triboelectric generator of claim 5 , wherein the metal oxide is zinc oxide (ZnO).

7 . The fibrous triboelectric generator of claim 5 , wherein the coating layer consists of a nonconductive polymer.

8 . The fibrous triboelectric generator of claim 2 or claim 7 , wherein the nonconductive polymer consists of one or more selected from the group consisting of polydimethylsiloxane (PDMS), polytetrafluoroethylene (PTFE), and polyvinylidene fluoride (PVDF).

9 . The fibrous triboelectric generator of claim 1 further comprising a second textile that is placed on a facing side of the first textile, where the second electrode layer is positioned therebetween and formed on a surface of the second textile.

10 . An electronic stimulator using triboelectricity, the electronic stimulator comprising:
a first textile; a first electrode layer that is formed on a surface of the first textile; a friction layer that is formed on a surface of the first electrode layer, has a surface with a concavo-convex structure, and is able to be electrically charged by friction; a second electrode layer that is able to undergo friction with the friction layer; a first pad that is electrically connected with the first electrode layer; and a second pad that is electrically connected with the second electrode layer.

11 . The electronic stimulator of claim 10 , wherein the friction layer consists of a nonconductive polymer.

12 . The electronic stimulator of claim 10 , wherein the friction layer includes:
a metal oxide that protrudes from a surface of the first electrode layer; and a coating layer that coats a surface of the metal oxide and the surface of the first electrode layer.

13 . The electronic stimulator of claim 10 further comprising a second textile that is placed on a facing side of the first textile, where the second electrode layer is positioned therebetween and formed on a surface of the second textile.

14 . A clothes for generating triboelectricity, the clothes comprising:
a first textile and a second textile that are disposed to face each other; a first electrode layer that is formed on a surface of the first textile on a facing side of the second textile; a friction layer that coats the first electrode layer, has a surface with a concavo-convex structure, and is able to be electrically charged by friction; and a second electrode layer that is formed on a surface of the second textile on a facing side of the first textile, and is able to undergo friction with the friction layer.

15 . The clothes of claim 13 , further comprising:
a first pad that is electrically connected with the first electrode layer; and a second pad that is electrically connected with the second electrode layer.
