Piezo-magnetic energy harvesting from movement of the head

[摘要] This paper reports the design, modeling, optimization and testing of the piezomagnetic energy harvester that is capable of converting non-harmonic movement of the human head into electricity. The rolling magnet and doubly-clamped piezoelectric configuration of the device makes the energy harvesting from small-amplitude and low-frequency movements of the human head efficient. In addition, the device can inconspicuously be integrated with the glasses. the experimental results show that the energy harvester device could deliver the maximum instantaneous power of 0.5 μW to the impedance matched resistive load.
