PVEH and Magnetic Interaction

This chapter presents some computational studies for the exploitation of magnetic force as a frequency up-conversionFrequency up-conversion mechanism in vibration-based piezoelectric energy harvestingPiezoelectric energy harvesting. First, a device concept is presented in which the FuC occurs through the interaction of a low-frequency oscillating mass and a piezoelectric transducer. Next, a magnetic interaction mechanism based on the free fallFree-fall mechanism of the seismic mass, no longer oscillating but simply moving in a stroke, is investigated. The electromagnetic transduction for the latter mechanism is also briefly investigated.
