Abstract

A manual device comprising a longitudinal prehension body and a pad for a capacitive screen mounted on one end of said body, wherein the body is insulating, while the pad is conductive, and a rod of polymer material filled with at least one conductive material and/or comprising a conductive coating is electrically in contact with the pad and extends longitudinally inside the body.

First claim

The invention claimed is:

1. A manual device comprising:
a longitudinal prehension body and a pad for a capacitive screen mounted on one end of the body, wherein the body is insulating, while the pad is conductive,
a rod that comprises material selected from the group consisting of a polymer material that is filled with at least one conductive material, a polymer material that comprises a conductive coating, and any combination thereof, the rod being electrically in contact with the pad and extends longitudinally inside the body, and
wherein the body has an outside surface with a layer of conductive material being arranged on the outside surface, the layer being insulated from the pad, said layer of conductive material being only on a part of an outside surface of said longitudinal prehension body.

2. A device according to claim 1 , wherein the rod extends over more than 10% of the length of the body.

3. A device according to claim 1 , wherein the pad is mounted on the body via a conductive base, while the rod is electrically in contact with the pad via the base.

4. A device according to claim 3 , wherein the rod and the base form a single piece.

5. A device according to claim 1 , further comprising a writing tip or the equivalent.

6. A device according to claim 1 , wherein the body is made of: insulating polymer material, wood, ceramic, glass, or their equivalents.

7. A device according to claim 1 , wherein the layer extends at least in part in longitudinal overlap with the rod.

8. A device according to claim 1 , wherein the layer extends over at least 30% of the length of the rod.

9. A device according to claim 1 , wherein the layer comprises a metal foil or a conductive laminate.

10. A device according to claim 1 , wherein the rod is spaced apart from the body.

11. A device according to claim 1 , wherein the rod and the body are substantially cylindrical, the rod and the body each having an outside surface of a substantially cylindrical shape, the radial distance between the outside surface of the rod and the outside surface of the body being less than 5 mm.

12. A device according to claim 1 , the device being of the passive type.

13. A manual device comprising:
a longitudinal prehension body and a pad for a capacitive screen mounted on one end of the body, wherein the body is insulating, while the pad is conductive,
a rod that comprises material selected from the group consisting of a polymer material that is filled with at least one conductive material, a polymer material that comprises a conductive coating, and any combination thereof, the rod being electrically in contact with the pad and extends longitudinally inside the body, and
a writing tip or the equivalent,
wherein the body has an outside surface with a layer of conductive material being arranged on the outside surface, the layer being insulated from the pad, wherein the writing tip is fed from a reservoir, said reservoir being located in full or in part inside the rod.

14. A manual device comprising:
a longitudinal prehension body and a pad for a capacitive screen mounted on one end of the body, wherein the body is insulating, while the pad is conductive,
a rod that comprises material selected from the group consisting of a polymer material that is filled with at least one conductive material, a polymer material that comprises a conductive coating, and any combination thereof, the rod being electrically in contact with the pad and extends longitudinally inside the body, said rod being a hollow cylinder, and
wherein the body has an outside surface with a layer of conductive material being arranged on the outside surface, the layer being insulated from the pad.
