【 摘 要 】

This paper reports a parametric study of a multi degree of freedom vibrations magnetic energy harvester for transport application. Two aspects were studied. First we focused on downsizing capability of our harvester. We showed that the output power is proportional to the scavenger volume. Typical output power of 100 μW/cm3was demonstrated with 0.5g harmonic excitation and 5 μW/cm3when harvesters were excited by the movement of a trolley. Then we studied the effect of the coil winding to optimize both output power and output voltage. Raising the number of turns and the wire radius can increase output power. Output voltage is only related to the number of turns.
