Flexible RFID tag having a helical antenna and an object gripped within the helical antenna

A flexible radio frequency identification (RFID) wire tag comprising:

• an RFID chip;
• and
• a helical antenna associated with the RFID chip, wherein:
• the helical antenna is configured to be deformed from an initial helical configuration in which an open interior of the helical antenna has a first diameter to an expanded helical configuration in which the open interior of the helical antenna has a second diameter that is greater than the first diameter;
• the flexible RFID wire tag is configured to return the helical antenna from the expanded helical configuration toward the initial helical configuration, such that an object or a portion of an object positioned within the open interior of the helical antenna in the expanded helical configuration and having an outer diameter greater than the first diameter will be contacted and gripped by the flexible RFID wire tag as the helical antenna is returned from the expanded helical configuration toward the initial helical configuration, and
• at least one gripping element configured to have a greater sliding friction with the object or the portion of the object than the helical antenna, wherein the at least one gripping element is positioned along a length of the helical antenna, and wherein the at least one gripping element is formed of any one of:
• a rubber and a silicone material.
