A label for marking and remote detection of objects has a capsular housing (10, 11) of a material, which in non-magnetic, electrically non-conductive as well as resistant against external influence, the housing consisting of a lower portion (10) and a cover (11), between which a cavity (12) is formed, and at least one elongated sensor element (13) arranged in the cavity (12), the sensor element being made from an amorphous magneto-elastic material with high magneto-mechanical coupling. On all its interior surfaces facing the cavity (12), the housing (10, 11) is provided with fine bristles or fibers (14), the number, length and density of which have been selected for receiving the sensor element (13) in a way, such that the sensor element (13) when resonating, will maintain its straightness and will be allowed to oscillate in the longitudinal direction thereof essentially free from losses, with no harmful influence from bending or torsional forces, and with no risk of losing energy due to friction or contact with the inside of the housing (10, 11). |
