1. A dry EEG sensor, comprising (11) (4)

at least one electrical contact for contacting the skin of a user, each electrical contact being connected to electrical circuitry to process any detected signals;

wherein the at least one electrical contact is mounted in a flexible layer mounted on a part of a device in which the EEG sensor is mounted, wherein the flexible layer permits movement in all directions with the user's skin when the user's skin moves relative to the device,

wherein the flexible layer supports the electrical contact to press the electrical contacts against the skin of the user,

wherein the electrical contacts pass through the flexible layer and a void exists between the electrical contacts and the device.

2. A dry EEG sensor as claimed in claim 1, wherein the flexible layer is formed from silicone. (0)

3. A dry EEG sensor as claimed in claim 1, wherein the flexible layer is provided with concertina regions to permit movement of the electrical contacts. (0)

4. A dry EEG sensor according to claim 1, wherein the flexible layer is formed from silicone and is provided with concertina regions to permit movement of the electrical contacts. (0)

5. A dry EEG sensor according to claim 1, further comprising a barrier layer surrounding the at least one electrical contact. (0)

6. A dry EEG sensor according to claims 1, wherein the at least one electrical contact is mounted in a bobbin. (0)

7. A dry EEG sensor according to claim 1, wherein the flexible layer is formed from silicone and is provided with concertina regions to permit movement of the electrical contacts, and wherein the at least one electrical contact is mounted in a bobbin. (0)

8. A dry EEG sensor as claimed in claim 1, wherein in the void between the electrical contacts and the device, a resilient material is positioned between the at least one electrical contact and a part of a device in which the EEG sensor is mounted; and (0) (1)

9. A dry EEG sensor according to claim 1, wherein at least one EEG sensor is sufficiently elongate to sense signals on a scalp and reaches through hair on a user's head to make contact with skin. (0)

10. A dry EEG sensor according to claim 1, wherein the device is a set of headphones, and in use at least one EEG sensor contacts a region of a user's ear. (0)

11. A dry EEG sensor according to claim 1, further comprising a barrier layer surrounding the at least one electrical contact through which the at least one electrical contact protrudes to contact the user. (0)

12. A set of headphones in which at least one EEG sensor according to claim 1 is mounted. (0)

13. A electroencephalography EEG sensor mounted in a set of headphones, comprising: (0) (4)

a flexible layer which permits movement in all directions; and

at least one elongate electrical contact for contacting the skin of a user,

wherein the at least one electrical contacts are mounted in the flexible layer and the flexible layer provides support for the at least one electrical contacts,

wherein in use the EEG sensor contacts a region of an ear of the user.

14. An EEG sensor mounted in a set of headphones, comprising (6) (3)

at least one electrical contact for contacting the skin of an ear of a user;

a resilient material positioned between the at least one electrical contact and part of a set of headphones in which the EEG sensor is mounted; and

a low-friction material positioned between the at least one electrical contact and the resilient material.

15. An EEG sensor according to claim 14, further comprising a barrier layer surrounding the at least one electrical contact. (0)

16. An EEG sensor according to claim 14, further comprising a bumper within the resilient layer to prevent excessive movement of the at least one electrical contact. (0)

17. An EEG sensor according to claim 14, wherein the resilient layer is formed of foam. (0)

18. An EEG sensor according to claim 14, further comprising a barrier layer surrounding the at least one electrical contact, wherein the barrier layer is formed of fabric. (0)

19. An EEG sensor according to claim 14, further comprising a barrier layer surrounding the at least one electrical contact, wherein the barrier layer is formed of silicone. (0)

20. An EEG sensor according to claims 14, wherein the at least one electrical contact is mounted in a bobbin. (0)
