Abstract

In this era of technology development, the main concern is the need to identify new energy sources. One of the sectors that have attracted much interest is devices that are able to convert other types of energy into electrical energy. The purpose of this project is to design a piezoelectric generator with different configurations to get an optimum efficiency of energy conversion from kinetic energy to electrical energy. This project also will show that the presence of waste energy from human foot steps while walking on the floor which is able to transform into useful electrical energy. Systems involved in this project is energy harvesting allows the conversion of dynamic compression of piezoelectric material attached to the floors by people walking on it. However, there is a limitation on the amount of energy harvesting from piezoelectric which needs to be improved on the output power generation. The output power will be compared for each condition where all the piezoelectric strip were connected in parallel and series. The power generated by a piezoceramic is in the form of AC which is not directly used for battery charging, hence a rectifier circuit is designed to convert the AC voltage to DC and generating power which is stored in a capacitor. Then, the energy produced can be utilized to light up some LED miniature or electronic devices
