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 (based on coal, Ignite, and oi ....etc

Abstract-

Comparator-controlled power switch has been widely used to improve power efficiencies of discontinuous-conductionmode (DCM) buck regulators. Some major design challenges are capabilities of the comparator to operate at low voltage and dissipate low power for low-voltage DCM ....etc

A guidance system for helping the blind find the way is described. Means to generate modulated signals of different frequencies is there and also a means to amplify and transmit these signals through conductors along the path of the journey. A cane recieves the signals through oscillating means responsive to each signal. It also comprises an amplifier to amplify the signals so that it can be detacted by many persons carrying such recievers along the path.

An oscillator, amplifier and a pulse generator makes up the reciever stick. This syst ....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

POWER SUPPLY FOR ELECTRIC TRACTION DRIVES
ABSTRACT
Electric Traction
There is a wide variety of electric traction systems around the world, which have been built according to the type of railway, its location and the technology available at the time of the installation. Many installations seen today were first built up to 100 years ago, some when electric traction was barely out its diapers, so to speak, and this has had a great influence on what is seen today.
In the last 20 years there has been a gigantic acceleration i ....etc

Abstract

Electric training diapers are electrified diapers designed to discourage and punish bedwetting. When the diaper is used, the sensor detects the wetness and administers an electric shock to the wearer's genitals and buttocks. These diapers were developed for adolescent and adult bedwetters and are not recommended for use on children.Electric training diapers consist of regular cloth or disposable diapers fitted with electrodes and a wetness sensor. These attachments should not be in direct contact with the skin but rather contained u ....etc
