Abstract
A Radio Frequency Identification (RFID) system according to one embodiment includes communication circuitry for enabling wireless communication with an RF reader; energy harvesting circuitry for generating an electric current from RF energy; a sensor loop coupled to the energy harvesting circuitry; and a status register coupled to the sensor loop for indicating a broken or unbroken status of the sensor loop. A method according to one embodiment includes generating an electric current in a Radio Frequency Identification (RFID) device, the current energizing a sensor loop; detecting a status of whether the sensor loop is broken or unbroken; storing the status in at least one of a status register and a nonvolatile memory; receiving a query from an RFID reader for the status; and sending the status to the RFID reader.
