Paper Abstract
This paper investigates the potential of designing a vibratory energy harvester which utilizes a ferrofluid sloshing
in a seismically excited tank to generate electric power. Mechanical vibrations change the orientational order of
the magnetic dipoles in the ferrofluid and create a varying magnetic flux which induces an electromotive force
in a coil wound around the tank, thereby generating an electric current according to Faraday's law. Several
experiments are performed on a cylindrical container of volume 5x10-5 m3 carrying a ferrofluid and subjected
to different base excitation levels. Initial results illustrate that the proposed device can be excited at one or
multiple modal frequencies depending on the container's size, can exhibit tunable characteristics by adjusting
the external magnetic field, and currently produces 28 mV of open-circuit voltage using a base excitation of
2.5 m/s2 at a frequency of 5.5 Hz.
