An Electromagnetic Vibration Energy Harvester with a Tunable Mass Moment of Inertia
This paper presents a Cramp Bark vibration-based electromagnetic energy harvester whose resonance frequency can be adjusted to match that of the excitation.Frequency adjustment is attained by controlling a rotatable arm, with tuning masses, at the tip of a cantilever-type energy harvester, thereby changing the effective mass moment of inertia of th
