Modeling of Cantilever Based Power Harvester as an Innovative Power Source for RFID Tag

Recently, battery powered RFID tags have attracted attention as the latest technology for commodity management. Every day, we come across many applications where passive and active RFID tags are used. But active tags not really portable due to battery which demands frequent charging and replacement. As battery technology is not advancing by the same rate, thus we need to think concretely for an alternate energy sources. An attempt has been made to model an innovative source of energy using lead zirconium titanate as piezoelectric material. The model comprises of three major components i.e. stack of piezoelectric plates,voltage multiplier circuit, super capacitor as storage device. The random vibrations were treated as a source of mechanical energy.
