Abstract

An electrostatic energy generator may include one or more first tire cord fabrics each including a conductive material which is a wire-shaped electrode and a non-conductive material, the non-conductive material configured to surround an outer peripheral surface of the conductive material, and one or more second tire cord fabrics each including a conductive material which is a wire-shaped electrode, and a material configured to surround an outer peripheral surface of the conductive material that is different from the non-conductive material of the first tire cord fabric, wherein the first tire cord fabric and the second tire cord fabric are arranged in a longitudinal direction so as to be in contact with each other and form a bundle, such that frictional electricity is generated due to a friction between the first tire cord fabric and the second tire cord fabric.

Claims

1. An electrostatic energy generator, the generator comprising:

one or more first tire cord fabrics each including a conductive material which is a wire-shaped electrode and a non-conductive material, the non-conductive material configured to surround an outer peripheral surface of the conductive material; and

one or more second tire cord fabrics each including a conductive material which is a wire-shaped electrode, and a material configured to surround an outer peripheral surface of the conductive material that is different from the non-conductive material of the first tire cord fabric,

wherein the first tire cord fabric and the second tire cord fabric are arranged in a longitudinal direction so as to be in contact with each other and to form a bundle, such that frictional electricity is generated due to a friction between the first tire cord fabric and the second tire cord fabric, and

wherein any one of the first tire cord fabric and the second tire cord fabric is disposed on a center of the bundle and the other tire cord fabric is disposed on a circumference thereof, such that the tire cord fabrics disposed on the circumference are disposed so as to surround the tire cord fabrics thereinside.

2. The generator of claim 1, wherein the first tire cord fabric and the second tire cord fabric are twisted in the bundle.

3. The generator of claim 1, comprising a plurality of bundles, such that frictional electricity is generated due to a friction between the first tire cord fabric and the second tire cord fabric and a friction between the bundles of the plurality of bundles.

4. The generator of claim 3, wherein the bundles of the plurality of bundles are twisted with each other.

5. The generator of claim 3, wherein, in the plurality of bundles, each of the bundles is made of only any one of the first tire cord fabric and the second tire cord fabric.

6. The generator of claim 5, wherein in the plurality of bundles, each of the bundles is made of tire cord fabrics which are different from each other.

13. A tire cord comprising the electrostatic energy generator using the tire cord fabric according to claim 1.

14. A tire comprising the tire cord of claim 13.

15. A tire pressure measurement sensor comprising the tire of claim 14,

wherein electric energy generation signals generated from the electrostatic energy generator are collected during a driving of the tire, and

wherein an air pressure of the tire is determined to be normal or not normal.

7. An electrostatic energy generator, the generator comprising:

one or more first tire cord fabrics each including a conductive material which is a wire-shaped electrode and a non-conductive material, the non-conductive material configured to surround an outer peripheral surface of the conductive material; and

one or more second tire cord fabrics each including a conductive material which is a wire-shaped electrode,

wherein the first tire cord fabric and the second tire cord fabric are arranged in a longitudinal direction so as to be in contact with each other and to form a bundle, such that frictional electricity is generated due to a friction between the first tire cord fabric and the second tire cord fabric, and

wherein any one of the first tire cord fabric and the second tire cord fabric is disposed on a center of the bundle and the other tire cord fabric is disposed on a circumference thereof, such that the tire cord fabrics disposed on the circumference are disposed so as to surround the tire cord fabrics thereinside.

8. The generator of claim 7, wherein the first tire cord fabric and the second tire cord fabric are twisted in the bundle.

9. The generator of claim 7, comprising a plurality of bundles, such that frictional electricity is generated due to a friction between the first tire cord fabric and the second tire cord fabric and a friction between the bundles of the plurality of bundles.

10. The generator of claim 9, wherein the bundles of the plurality of bundles are twisted with each other.

11. The generator of claim 10, wherein, in the plurality of bundles, each of the bundles is made of only one of the first tire cord fabric and the second tire cord fabric.

12. The generator of claim 11, wherein in the plurality of bundles, each of the bundles is made of tire cord fabrics which are different from each other.
