Abstract
This paper deals with Energy Harvesting using a part of physical energy which is generated by pulldown actions. From a point of energy harvesting view, though it is difficult to regenerate constant energy during pulldown exercise unlike cyclic exercise and running machine exercise, it is possible to regenerate some energies to charge batteries for mobile phones. To investigate possibility of energy harvesting during pulldown exercise, a voltage regulation experiment was performed with a converter circuit and a motor which is attached to the exercise equipment. And we conclude that energy harvesting is possible although its small quantity during pulldown exercises.
