CLAIMS

1 . A sensor (1 ) to be placed in contact with the skin (12) of an user for acquiring physiological signals which comprises:

a) a conductive layer (2) comprising at least conductive fibers to be placed in contact with the skin (12) for receiving physiological signals;

b) an electrical connector (5) connected to the conductive layer;

characterized in that the conductive layer comprises a plurality of orificies (6) filled with an silicone rubber throughout the conductive area.

2. The sensor (1 ) according to claim 1 , wherein the conductive layer (2) comprises at least an electrode (3) and a track (4).

3. The sensor (1 ) according to claim 2, wherein the track (4) is covered with an insulating material (8).

4. The sensor (1 ) according to any of the claims 2-3, wherein the electrode (3) is a conductive fabric comprising conductive fibers and non conductive fibers.

5. The sensor (1 ) according to any of the claims 2-4, wherein the track (4) is a conductive fabric comprising conductive fibers and non conductive fibers.

6. The sensor (1 ) according to any of the claims 1 -4, wherein the conductive fibers are made of silver coated nylon and the non conductive fibers are made of nylon.

7. The sensor (1 ) according to any of the claims 1 -6, wherein the silicone rubber is a silicone rubber with molecular weight comprised between 400 g/mol and 600 g/mol.
