摘要:
Excess radio-frequency (RF) power storage in RF identification (RFID) tags, and related systems and methods are disclosed. The RFID tag is configured to operate with RF power received in wireless RF signals from a RFID tag antenna if received RF power meets or exceeds an operational threshold power for the RFID tag. The RFID tag is also configured to store excess energy derived from excess received RF power in an energy storage device if the received RF power exceeds the operational threshold power for the RFID tag. Thus, when RF power received by the RFID tag is not sufficient for operation, the RFID tag can operate from power provided by previously stored excess energy in the energy storage device.
