Abstract
In last few years low power electronic devices have been increased rapidly. The devices are used in a large number to comfort our daily lives. With the increase in energy consumption of these portable electronic devices, the concept of harvesting alternative renewable energy in human surroundings arise a new interest among us. In this project I try to develop a piezoelectric generator. That can produce energy from vibration and pressure available on some other term (like people walking ). This project describes the use of piezoelectric materials in order to harvest energy from people walking vibration for generating and accumulating the energy. This concept is also applicable to some large vibration sources which can find from nature. This project also represents a footstep of piezoelectric energy harvesting model which is cost effective and easy to implement.

A day’s energy is one of the most important issues around the world
The energy came from natural sources, termed as renewable energy
Micro energy can produce from those natural sources that are called micro energy harvesting
Summary
A day’s energy is one of the most important issues around the world. Especially in Bangladesh energy crisis is a big problem. Micro power supply needs is increasing greatly with time as our technology is moving to the micro and nanno fabrication levels Our discussion on this is based on generating micro energy from vibration and pressure using piezoelectric material. Though piezoelectric material has the property of converting mechanical energy into electrical energy but developing piezoelectric generators is challenging because of their poor source characteristics (high voltage, low current, high impedance) and relatively low power output [6]. In the past these challenges have limited the development and application of piezoelectric generators. I managed with our mechanical structure to give the strength and got maximum output as mW range (Figures 1-7)
