GENERATING ELECTRICITY USING PIEZOELECTRIC MATERIAL


INTRODUCTION

The recent fluctuations on the price of petroleum have affected worldwide economics which
has forced an increased in the price of other items including food. Some even linked the recent
collapse of few financial institutions in countries such US and theUKto the recent increased in
this price. This shows that we are too dependent to petroleum as a source of electrical power.
Besides, petroleum as a source of electrical energy has contribute ....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

Generating Electricity using Power Humps
Introduction
 Due to day-to-day increase in population and lessen of the conventional sources, it becomes necessary that we must depend on non-conventional sources for power generation.
 Energy crisis is a significant bottleneck (or price rise) in the supply of energy resources in an economy. It usually refers to the shortage of oil and additionally to elect ....etc

The use of road humps for moderating speeds on Urban streets


The use of road humps for moderating speeds on
Urban streets


Road humps are devices placed in the path of traveling vehicles. They are used in many communities to keep a uniform and low speed on a residential street or to reduce speeds at specific locations, such as intersections or pedestrian crosswalks. While the effectiveness of road humps in moderating speeds at the site of installation is generally considered proven, the actual adoption of the device re ....etc
