A floor covering comprises: a surface layer (4) comprising a plurality of conductive segments (12) suitable for being powered electrically; an at least partially electrically insulating intermediate layer (6) comprising a plurality of holes (14) distributed in a substantially regular manner in such a way that the average distance between a hole (14) and the hole (14) closest thereto is between approximately 5 cm and 20 cm; and a base layer (8) comprising a plurality of electrical contacts (16) at least some of which correspond to the holees (14) of the surface layer (4) and are connected to an electronic controller (10). The surface layer (4), the intermediate layer (6), and the base layer (8) are arranged one on top of the other in this order, and are positioned in such a way that at least some of the conductive segments (12) are arranged at least partially facing a hole (14) of the intermediate layer (6), and that these conductive segments (12) react to a pressure by approaching the corresponding electrical contacts (16) of the base layer (8), the electronic controller (10) being also arranged so as to selectively emit a warning signal, depending on a condition comprising the number of conductive elements (16) to which it is connected, which are close to a conductive segment (12). |
