Abstract: A heart activity measurement device for an individual including: a processing unit; at least one measurement cable, including a first end suited for connection to the processing unit in order to form an input for an electrical potential, and a second end; a support, ready for an individual to wear, where the support supports the cable so as to keep a predefined path for the cable relative to the skin of the individual when the support is worn. The cable is laid out such that when the support is worn, any contact between an electrically conducting part of the cable and the skin of the individual is prevented. The second end of the cable does not have any electrode for contact with the skin. The support is further laid out for keeping a predefined spacing between a measurement portion of the cable and the skin of the individual.

Abstract: A wearable device including a garment portion including an inner textile layer, and an electronic portion including at least one electrode based on an electrically conductive elastomer, stitched to the inner textile layer and/or to a support layer attached to the inner textile layer. The garment portion is designed to at least partially surround a person's limb such that the inner textile layer and the at least one electrode are kept at least partially in contact with the person when the device is worn.

Abstract: An electrode for acquiring electroencephalogram signals of a user includes a base and a plurality of legs extending from the base at first extremity. The legs include a second extremity covered with an electrically conductive material. The second extremity includes a smaller cross-section than the first extremity of the legs so the legs can penetrate through hair of the user. The legs elastically flex such that, when the electrode is applied on a user's head, the electrically conductive material of the second extremity contacts a scalp of the user, wherein the base is of cuboid shape having two side faces, the legs being directly attached to the side faces of the base, the legs being symmetrically attached to the base with respect to a longitudinal axis and the legs attached to a side face of the base facing the legs attached to the other side face of the base.
