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

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 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 can achieve this optimal power flow.

The harvesting cir ....etc

by using smart sensors (which following pricipal of Piezo electricity) we can make electricity here in this project we will place smart sensors in the high dense roads (such as traffic jam places in some cities) as this sensors convert static energy of vehicles into power and this can be used for lightning the streets and so on.and similarly by using smartsensors we can extend its application for vehicle tracking, navigation and so on.Using the same smart sensors we need to place those by making 8slots in the wheel of goods train (since indianr ....etc

POTENTIAL OF PIEZO ELECTRIC ECOFLOOR FOR GENERATION OF ELECTRIC POWER


The need to generate electricity is the demand for today’s life because of the fact that even if the planet doubles the amount of solar and wind power available, there would still be a shortage of clean electricity. Comparison of different forms of commercial power generation by use of the fuel cycle methods developed in European studies shows that the health burdens are extreme in areas where power stations (base ....etc

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
