15 October 2012 The research of energy harvesting system use in RFID tag
Author Affiliations +
With the decreasing power requirement of microelectronics, environmental energy sources can begin to replace batteries in the RFID tag. In this spirit, a novel resonate piezoelectric device is developed in the combined structure of SAW and FBAR which used for generating electrical power “parasitically” while the RFID tag is moving. The relationship of the different vibration mode to the power density of harvesting energy is analyzed and the relative merits and compromises are discussed. In the last, the suggestions are proposed for improvements and potential applications in the RFID.
