Abstrakt

A new micro electromagnetic energy harvester with iron frame based on mechanical spring vibration is proposed in this paper for increasing the output voltage. The dynamic model of this new structure and an analytical method for maximizing the output voltage and power from low-frequency vibration sources are derived. Finite Element Analysis (FEA) is carried out for validation. This new structure achieves normalized power density of 1651.3 μWcm -3 g - 2 and the output power at 10.1 Hz can reach 446.5 μW with 0.52 g acceleration amplitude. It demonstrates superior performances compared to previously reported low frequency energy harvesters.
