mobile charging using sound energy pdf

Hello, I'd like to get details and information about converting sound to electrical energy for a school project. It is really hard to find a standard protocol for this project especially that we lack knowledge in technology. If you could provide it, it's really appreciated. Thank you!

mobile charging using sound energy
Nowadays mobile phones are
It is necessary for all human beings. And also
This is a 21st century power plays
A key role in the electrical equipment
Mobile phones, laptops etc, it is very difficult to
To imagine life without these tools. Go to
Population abuse power
Need even more consumption. Energy
Is the main source of power generation. We
In this world are bombarded with energy. Therefore
It is necessary to increase the power supply
Power and it is necessary for us to find
Another alternative methods to produce
Electrical energy.
When we think of another
method we thinks about solar energy, wind
energy, but we forgot sound energy. In this
century the main problem facing in the
metropolitan cities are noise pollution. So we
have an idea to convert this sound
energy into electrical energy.
This process works This theory of the piezo electric effect it.
In the process we have a Nana piezo electric wiring harness
Which are made of zinc oxide. Its length
Each wire is 100-200 nanometer
Approximately equal to the width of our hair. So it
Very sensitive to vibration sound. These Nano
Wires are sandwiched between two sound
Pad to absorb. Are the ends of the pad
Gold electrode is connected.

\INTRODUCTION:
Cellular telephone technology became
commercially available in the 1980’s.Since
then, it has been like a snowball rolling
downhill, ever increasing in the number of
users and the speed at which the technology
advances. When the cellular phone was first
implemented, it was enormous in size by
today’s standards. This reason is two-fold; the
battery had to be large, and the circuits
themselves were large.

Mobile phones charged using sound Orange, Official Communications Partner for the Glastonbury Festival currently being held in the United Kingdom, has announced their latest invention in the world of mobile charging technology with an innovative gadget that powers mobile phones using sound. Following months of planning and development, the prototype, named the Orange 'Sound Charge' has been produced in conjunction with renewable energy experts at GotWind. The eco charging device uses an existing technology in a revolutionary way by reversing the use of piezoelectric film, allowing people to charge their mobile phones whilst enjoying their favorite headline act at Glastonbury. Usually found in modern hi-fi speakers, an A4 panel of the modified film is housed inside a t-shirt which then acts much like an oversized microphone by 'absorbing' invisible sound pressure waves. These sound waves are converted via the compression of interlaced quartz crystals into an electrical charge, which is fed into an integral reservoir battery that in turn charges most makes and models of mobile phone. As the 'device' is worn, a steady charge is able to be dispensed into the phone via a simple interchangeable lead which fits most handsets. After a weekend at Glastonbury the Orange Sound Charge will almost certainly be in need of a good scrub, so the Piezoelectric film panel and electronics are all fully removable to enable the shirt to be washed. The development team behind the device estimate that when used at the festival with sound levels of around 80dB (roughly the same as a busy street), the Orange Sound Charge will generate up to 6 watt hours (W/h) of power over the course of the weekend - enough to charge two standard mobile phones or one Smartphone. Of course festival goers will also be able to plug in their phone for a quick 'top up' charge whenever they need it. Andrew Pearcey, Head of Sponsorship at Orange UK said: "In a vibrant festival environment such as Glastonbury, sound is such an obvious medium that it seemed like a natural fit to use it in the development of this year's prototype. Orange's commitment and ethos around innovation is as strong as ever and we envisage that this pioneering technology could really change the face of mobile charging in environments where eco charging solutions need to be found. It could even influence trends in fashion, with designers looking to integrate this passive charging solution into clothing." Orange will also be conducting live testing on site at the festival to see which acts are the 'best to charge to' and the team will be testing the device throughout the weekend to advise festival goers on which acts will give your phone the quickest charge. The Orange Sound Charge is the latest eco charging innovation in Orange's continued commitment to researching and developing alternative charging solutions. Previous projects have included 2010's Power Wellies (Power generating sole), winner of Time Magazine's '50 Best Inventions of 2010' which converted heat into current to keep people connected at last year's festival and the Dance Charger(Dance power for mobile phones) that drew upon kinetic energy to create power. The Orange Sound Charge is still in developmental stages.
