Cataloged from PDF version of thesis report. Includes bibliographical references (page 63-65). The aim of this thesis was to design and an efficient energy harvester from ambient vibrations. An energy harvester is merely a device that will convert ambient energy into some usable electrical energy. In this work we designed a vibration energy harvester using electromagnetic transduction mechanism. The system consists of a fixed (movable) magnet and a movable (fixed) coil attached to a spring. When under vibration, relative motion between the fixed magnet and a moving coil or between the moving magnet and a fixed coil created a time varying flux linkage to the coil, thus inducing an electro-magnetic force. The electrical energy thus extracted from these vibrations need to be stored, using a battery charger circuit, and later on this may be used to drive electronic gadgets, self-powered micro-systems and wireless sensor network. In this work we designed the electro-mechanical energy harvesting system for optimum performance for a range of vibration energy and frequency, starting from 300-350Hz and studied the impact of difference device parameters, such as, size of the mass (510mg), stiffness of the spring, number of turns and dia of the coil. A charge controller circuit to store the generated electrical energy can be designed for implementation. Tasfia Rahman Syedur Rahman Sakir Shawzia Dewan Onna B.
