Lifetime Extension of Higher Class UHF RFID Tags using special Power Management Techniques and Energy Harvesting Devices
Abstract. Enhanced RFID tag technology especially in the UHF frequency range provides extended functionality like high operating range and sensing and monitoring capabilities. Such functionality requiring extended system structures including data acquisition units, real time clocks and active transmitters causes a high energy consumption of the tag and requires an on board energy store (battery). As a key parameter of the reliability of an RFID system is the lifetime, the energy budget of the higher class tag has to be as balanced as possible. This can be achieved by using energy harvesting devices as additional power supply. The PowerTag 1 project and thus this paper proposes special power management mechanisms in combination with special energy storage structures interfacing energy harvesting devices and dealing with their special requirements. First various power management and power saving techniques are simulated and their performance is evaluated. In a second step different impl...
