This study designed an energy harvester with the function of simultaneous power generation and disturbing torque absorption. The dynamic behavior of the energy harvester is similar to centrifugal pendulum vibration absorbers; accordingly, the dynamic equations were derived using the Lagrange method. This paper discusses the absorption efficiency of the energy harvester at various disturbing frequencies. Simulation results show the maximum power of the proposed design to be 125.2 microwatt at 40 km/hr, and the reduction of oscillation amplitude is more than 50 percentages when the disturbing frequency is higher than 0.01 Hz.
