In this paper, we study energy harvesting from the mouse click motions of a robot ?nger and a human index ?nger using a piezoelectric material. The feasibility of energy harvesting from mouse click motions is experimentally and theoretically assessed. The ?ngers wear a glove with a pocket for including the piezoelectric material. We model the energy harvesting system through the inverse kinematic framework of parallel joints in a ?nger and the electromechanical coupling equations of the piezoelectric material. The model is validated through energy harvesting experiments in the robot and human ?ngers with the systematically varying load resistance. We ?nd that energy harvesting is maximized at the matched load resistance to the impedance of the piezoelectric material, and the harvested energy level is tens of nJ.
