A tactile sensor, in particular with function of artificial skin, having a sensing extended surface (5' ) adapted to detect contact and pressure with an external body (10), comprising a support layer (1), for example of flexible material, extending parallel to the sensing surface (5' ), having at least a light source that emits light at a prefixed angle with respect to the support layer (1) towards the sensing elements, an electronic circuit that connects the sensing elements and said at least one source, a layer of elastic transparent material (2) laid on the support layer (1) embedding the sensing elements, the light sources and the circuit; a shielding cover (4 e 5) that coats externally the layer of elastic transparent material, having externally to it said sensing surface (5' ). When an external body (10) presses on the sensing surface (5') an elastic deformation of the cover (4 e 5) and of the underlying layer of transparent material (2) is caused thus decreasing the intensity of light seen by the sensing elements. |
