Abstract

The invention relates to a filament or tape comprising a plurality of radio frequency identification integrated circuits (RFID), each one provided with independent antenna circuits, placed in sequence on a support.

Claims

1. Filament or tape comprising:

a sequence of one or more radio frequency identification integrated circuits (RFID tags), wherein each circuit has multiple antennas, lying on different planes whenever the geometry of the allows it (filament).

19. Filament or tape according to claim 1, wherein it has various degrees of elasticity either in parts or throughout its length.

20. Filament or tape according to claim 1, wherein it has various degrees of flexibility either in parts or throughout its length.

25. Gauzes or tampons or textile material that can be detected by radio frequency identification (RFID) technology means, wherein they provide one filament or tape according to claim 1.

26. Filament or tape comprising one or more tag circuits according to claim 1, where each antenna can have a different length.

27. Filament or tape comprising one or more tag circuits according to claim 1, where the multiple antennas can have common connection points with the integrated circuit.

28. Filament or tape comprising one or more tag circuits according to claim 1, where the independency of antennas is ensured by the presence of additional electronic circuits, for instance, but not limited to, using diods.

29. Filament or tape comprising one or more tag circuits according to claim 1, where in the case of antennas lying on different planes the angle between planes can be constant or variable.

30. Filament or tape comprising one or more tag circuits according to claim 1, where the integrated circuit can be physically detached from the antenna.

31. Filament comprising one or more tag circuits according to any of the previous claims, where the filament holding the antennas lying on different planes can be made by concentric layers.

32. Filament comprising one or more tag circuits according to claim 1, where the filament holding the antennas lying on different planes can be made folding or rolling one or more layers of any material.
