Abstract
A device (D′) for detecting the presence of a user includes: an electrode (12′), electrode control elements (13), and a low frequency antenna (11). The electrode (12′) is formed by a plurality of structural units (MA . . . MI), each structural unit (MA . . . MI) including: a conductive segment (A . . . I) defined by dimensions (Lx, lx, ex) and electrically connected at least to a conductive connection (CXY) defined by a position of connection with respect to the conductive segment (A . . . I). The structural units (MA . . . MI) are electrically interconnected by the conductive connections (CXY). At least two consecutive structural units (MA . . . MI) differ by: the dimensions (Lx, lx, ex) of the conductive segment (A . . . I) and/or the position of the conductive connection (CXY).
