Evaluation of the human vibration for autonomous power source

This paper reports an evaluation of a human vibration for autonomous power source that generate an electrical power from human vibration. The actual energy harvesting results from the MEMS (micro electromechanical systems) electret based energy harvester on the human body is also described. The harvester consists of the silicon grid structure, stripe-pattern charged electret material and support spring structures. Using a multipurpose data-logging device that can gather the 3-axis acceleration, pressure, humidity temperature and also harvesting voltage simultaneously investigate an actual harvested power from the human movement.
