Abstract

An inputting fingertip sleeve includes a sleeve and an inputting end. The sleeve has a curved linear structure. The inputting end is fixed on the sleeve. The inputting end includes a plurality of carbon nanotubes. A material of the sleeve is conductive, can be metal, alloy or conductive polymer. The inputting end is electrically connected with the sleeve.

First claim

What is claimed is:

1. An inputting fingertip sleeve comprising:
a curvilinear structure configured to receive a finger, a material of the curvilinear structure is metal or alloy;
an inputting end welded on and protruded from an outer surface of the curvilinear structure, wherein the inputting end comprises a supporter and a carbon nanotube structure located on a surface of the supporter, the carbon nanotube structure is a pure structure of carbon nanotubes consisting of a plurality of carbon nanotubes.

2. The inputting fingertip sleeve of claim 1 , wherein the curvilinear structure is a ring structure.

3. The inputting fingertip sleeve of claim 1 , wherein the plurality of carbon nanotubes is the carbon nanotube structure are joined end-to-end by van der Waals attractive force therebetween.

4. The inputting fingertip sleeve of claim 1 , wherein the plurality of carbon nanotubes in the carbon nanotube structure are entangled with each other.

5. The inputting fingertip sleeve of claim 1 , wherein the carbon nanotube structure comprises at least two carbon nanotube films stacked on each other.

6. The inputting fingertip sleeve of claim 1 , wherein the carbon nanotube structure comprises at least one carbon nanotube wire structure, a diameter of the at least one carbon nanotube wire structure is in a range from 100 nanometers to 1 micrometer.

7. The inputting fingertip sleeve of claim 6 , wherein the at least one carbon nanotube wire structure comprises the plurality of carbon nanotubes joined end-to-end.

8. The inputting finger-tip sleeve of claim 6 , wherein the plurality of carbon nanotubes in the at least one carbon nanotube wire structure are twisted with each other.

9. The inputting fingertip sleeve of claim 1 , wherein the carbon nanotube structure is one carbon nanotube wire structure comprising the plurality of carbon nanotubes joined end-to-end, the carbon nanotube wire structure spirals around the surface of the supporter.

10. The inputting fingertip sleeve of claim 1 , wherein the carbon nanotube structure comprises a plurality of carbon nanotube wire structures crossed with each other or woven with each other to form a net structure, the net structure covers the surface of the supporter.

11. The inputting fingertip sleeve of claim 1 , wherein the supporter is a hollow structure.

12. The inputting fingertip sleeve of claim 11 , wherein the hollow structure is filled with liquid material.

13. The inputting fingertip sleeve of claim 12 , wherein the liquid material is water or oil.
