Abstract
This seminar describes an approach to harvesting electrical energy from a mechanically excited piezoelectric element. A vibrating piezoelectric device differs from a typical electrical power source in that it has capacitive rather than inductive source impedance, and may be driven by mechanical vibrations of varying amplitude. The harvesting circuit consists of an AC-DC rectifier with an output capacitor, an electrochemical battery, and a switch-mode DC-DC converter that controls the energy flow into the battery. An analytical expre ....etc

Abstract

This paper describes an approach to harvesting electrical energy from a mechanically excited piezoelectric element. A vibrating piezoelectric device differs from a typical electrical power source in that it has a capacitive rather than inductive source impedance, and may be driven by mechanical vibrations of varying amplitude. An analytical expression for the optimal power flow from a rectified piezoelectric device is derived, and an energy harvesting circuit is proposed which ca ....etc

Now a days near about each man uses a mobile phone so the recharge this mobile phones is a most important task. We are trying to achieve a automatic mobile recharger machine which provides a 24 hour services without inter furnace or need of man. In our daily life we are recharge our mobile phone manually, that's why we should go to there shop / agencies, also these type of easy recharges are not available for 24hrs, also on long root or Expressways.

An automatic Mobile charger is one of the easiest ways to recharge our mobile anytime, anywhe ....etc

I. INTRODUCTION
The need for a wireless electrical power supply has spurred an interest in piezoelectric energy harvesting, or the extraction of electrical energy using a vibrating piezoelectric device. Examples of applications that would benefit from such a supply are a capacitively tuned vibration absorber ,a foot-powered radio tag and a Pico Radio .A vibrating piezoelectric device differs from a typical electrical power source in that its internal impedance is capacitive rather than inductive in nature, and that it may ....etc
