Claims

CLAIMS 1. Electrode (2;200) for recording a physiological electrical signal of a living being made of electrically conductive material and comprising a body (25) comprising a front surface (21) and a rear surface (22;222) of electrical contact, characterized in that the electrode further comprises a rigid mounting means (5,51;50) fixed to the body, at an edge of the rear surface of electrical contact and arranged so as to provide a removable mounting of the electrode on a recording sensor (1;100).

2. Electrode according to claim 1, characterized in that the material is a flexible electrically conductive material, in particular of the polymer type.

3. Electrode according to claim 1 or 2, characterized in that the rear surface (222) of the body is convex.

4. Electrode according to one of claims 1 to 3, characterized in that the rigid mounting means comprises a cylindrical ring (5; 50) fixed to the body.

5. Electrode according to claim 4, characterized in that the ring (50) has a thread (52) on a radially external surface.

6. Electrode according to claim 4 or claim 5, characterized in that the ring projects from the rear surface of the body.

7. Electrode according to one of claims 1 to 6, characterized in that the rigid mounting means comprises a stiffening washer (51).

8. Electrode according to one of claims 1 to 7, characterized in that the electrode further comprises a tool imprint (210) allowing removable mounting.

9. Electrode according to one of claims 1 to 8, characterized in that it further comprises pins (27) extending in projection from the front surface.

10. Recording sensor (1; 100) of a physiological electrical signal of a living being comprising a casing (4; 400) comprising a housing (42) and a printed circuit (3) positioned in the housing, characterized in that it further comprises an electrode according to one of claims 1 to 9 mounted removably on the casing, the rear surface being in electrical contact with a part (31) of the printed circuit.

11. Sensor according to claim 10, characterized in that the casing comprises an assembly means (41; 410, 411) complementary to the rigid means for mounting the electrode to achieve removable mounting of the electrode on the sensor.

12. Sensor according to claim 10 or 11, characterized in that the housing comprises a shielding means arranged so as to provide electromagnetic insulation.

13. Device (9) for measuring a physiological electrical signal intended to be worn by a living being, characterized in that it comprises at least one sensor according to one of claims 10 to 12.
