Abstract

This project is to construct a micro-power generator based on electromagnetic mechanism harvesting energy from direct air flow. The concept is to make a magnet-attached cantilever to oscillate in the presence of direct air flow. The oscillation happens when air travel and provide a force to push the cantilever downward in a repetition manner as a result of vortex generated underneath the cantilever. In order to generate electrical energy, a pair of magnet mounted on the cantilever and with a magnetic coil in between and fixed vertically at the tip of the cantilever is used to pick up the induced current. The E.M.F. voltage produced is directly proportional to the rate of change of magnetic flux. Experiment is carried out to analyze the output voltage produced by the micro-generator. The output power generated is able to activate small electronic device, this is shown by an LED indicator. A prototype for the micro power generator is constructed to demonstrate the capability of the generator in producing a sufficient electrical power by transforming kinetic energy to electrical energy. The direct air-flow is eco-friendly, less cost and renewable
