Abstract

Low level power output estimation from the vibration of car engine based on Micro-power generator is presented. Piezoelectric cantilever is used to harvest energy from the vibration. This material has an ability to scavenge the mechanical energy and transform into electrical energy. The electrical energy harvested is then charging capacitor after gone through full wave rectifier. The main objective of this project is to harvest energy from the environment, which is vibration from the car engine by developing a miniature generator using a piezoelectric cantilever. Storage capacitor would be used to store the energy so that the energy can be used for later uses or directly use from strain energy to electrical energy. Voltage regulator is used to provide an output dc voltage to maintain at a set value. The experimental results demonstrate the potential of the device applied to power up LED or LCD display and this application can be used as a self generate mini torch light for a mechanic to repair car engine in the dark.
