HISTORY It is one of the new developed technology. Researchers from Texas , &university of Houston

working on just such a concept back in 2008. They focused on a certain type of piezoelectric

material at around 21 nanometer thick. South korean researchers developed the effective

methode.

INTRODUCTION:

.

Sound energy ----------------Electrical energy

You have probably heard of renewably energy source like solar , wind,…

Have you ever heard about sound energy? Sound that always exists in our everyday life and

environments has been overlooked as a source. This motivated us to realize power generation by

turning sound energy from speech , music into electrical power.

Sound pollution is a great disadvantage that we come across our daily life.

But using this technology we can convert this great disadvantage to our use

WORKING PRINCIPLE:

It works on the principle of piezo electric effectric phenomenon.

The generation of an electric charge in certain non conducting material when they are subjected to mechnical stress is called piezoelectric effects (conversion of ME to EE)

What is piezo ?

Piezo used to describe the materials that accumulate a charge as a result of piezoelectric effect.

Piezo material , including crystals and ceramics generate a voltage in response to an applied mechanical force.

In reverse piezoelectric effect, these same material will lengthen or shorten in response to an applied voltage.

The voltage at force generated by piezo material are small and usually required amplification.

Components used in this technology:

Sound absorbing pads

Zn electrodes

Nano- generator

Sound absorbing pads:

•This technology uses piezoelectric materials

Features of sound absorbing plates:

Environment-friendly Shock resistantSound absorption Moisture proofHeat insulation, acid-base resistant

Zn electrodes: •These electrodes contains nano generator between them these

electrodes vibrate when sound waves hit on it .

Nano- generator:• It converts mechanical energy into

electrical energy.

Tiny strands of zinc oxide sandwitched between two electrodes.

A sound absorbing pad is placed on the top of of zinc oxide.

Nano generator is placed between the sandwitched zinc oxide electrode.

CONSTRUCTION

WORKING Sound waves are given as input and we get electrical

energy as output. When the sound waves are hit on the sound absorbing pad,

it will vibrate. This result in the tiny zinc oxide wires to compress and

release. This given to the nanogenerator. It convert the given ME To EE. The generated electrical energy is used to charge the

battery.

Sound wave of 100 decibels produced an electric current of about 50 millivolts

Normal conversation is conducted at about 60-70 decibels.

5-12 volts needed to properly charged the typical mobile device.

Advantages:•The mobiles can be charged not only by using our voice but also by employing background noise and music.

•Environmental noise like traffic, noise from trains, constructional noise can also be used to charge the battery.

DISADVANTAGE

It is expensive. Construction is difficult. Only possible for low voltage application.

Applications:Military purpose:•Since there may be no availability of charging at the place of their arraival . Unavailability of switch boards:•At Beach•At Forests

SCOPE FOR FUTURE Sound insulating walls near highways and airports to

produce electricity for lightning and other use. Recharge electric cars by tapping into the energy in traffic

noise. Both reducing noise levels and capturing wasted energy.

CONCLUSION Sound pollution is a great disadvantage that we come

across our daily life. By using this great disadvantage to our use. Voice usage to charge mobile phones creates a new era

with cleanly environment along with saving energy.
