Harvesting energy using a magnetic mass and a sliding behaviour

[摘要] This article presents the results of the study of two energy harvesting systems (EHS). One is constituted of a ferromagnetic mass put between two opposite electromagnets, while the other is constituted of a self-excited oscillator. The dynamical behaviour of both systems presents bursting oscillations. The characterization of EHS is also made, where the generated power is calculated in terms of mechanical load characteristics as well as in terms of the electric load.
