Verification of Self-Tuning 4DOF Piezoelectric Energy Harvester with Enhanced Bandwidth
In this paper, we present an analytical model to predict enhanced bandwidth for a
piezoelectric energy harvester with self-tuning, accomplished by a sliding mass. The model
predicts that by implementing asymmetry of different piezoelectric cantilever lengths, the
bandwidth can theoretically approach 60 Hz. Validation measurements demonstrate an
increased 3dB bandwidth up to 21 Hz with 150 mW, by configuration 23/17 mm in open
length–providing sufficient power for a ZigBee to continually transmit.
