Abstract:     This paper proposes a kinetic energy harvester designed to be implanted in a vehicle, which works at a low frequency associated with the movement of the automobile. Since the average frequency for a moving vehicle is around 30 Hz, the proposed prototype is designed to work with this low frequency. The concept of magnetic-force-driven energy harvesting is utilized to this prototype considering the car movements during routine driving. Finite element method was used to evaluate the magnetic field for the levitation magnet within the harvester. The simulation results for the resonant frequency and the voltage induced in a coil were 30 Hz and 3.5 V respectively. A prototype of the energy harvester was fabricated and tested. Experimentally, maximum open circuit voltage of 3 V was obtained and the resonant frequency of 28 Hz was observed.
