Patent number: 10842404Abstract: 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.Type: GrantFiled: June 12, 2018Date of Patent: November 24, 2020Assignee: DREEMInventors: Hugo Mercier, Quentin Soulet de Brugiere, Pierre Emerich, Martin Herrera, Camille Kerbaul, Hsin-Yin Chiang
