【 摘 要 】

A system and sensor provides for radio frequency identification (RFID)-enabled information collection. The system includes a ring-shaped element and an antenna. The ring-shaped element includes a conductive ring and an RFID integrated circuit. The antenna is spaced apart from the ring-shaped element and defines an electrically-conductive path commensurate in size and shape to at least a portion of the conductive ring. In an alternate embodiment, the sensor system further comprises a reference ring-shaped element in a fixed relationship with respect to the antenna, with the reference ring-shaped element defining another series circuit to include an electrically-conductive reference ring and a reference RFID integrated circuit. The system may include an interrogator for energizing the ring-shaped element and receiving a data transmission from the RFID integrated circuit that has been energized for further processing by a processor.
