Mobile phones are widely used in our daily life by giving us the freedom to communicate everywhere, anytime. Equipped with various facilities, it is available to people of all classes. The range of affordable and easy application make it a pleasure to use. In addition to communication, they also have other services programmed in them. The latest mobile phones are integrated with features like MP3 players, camera high resolution, high sound quality, 3 G technology and the list goes on. Mobile phones have become a hit among all categories of people, from children to teenagers to adults that allows them to enjoy a lifestyle techsavvy. These phones are considered style statement and give a touch sophisticated to your profile. The usefulness of this feature is more unknown. The growth rate of sales in India shows that nearly six million people buy cells each month in India. In fact, it is the largest market growing in the

companies have created so many different types of cell phone chargers so that we can easily and conveniently reload our batteries.world. A target of 800 million buyers in 2011. It can stop work and even cause dangerous situations. so we need to realize how it is important to have the battery power enough to fulfill our needs. But if the charger is misused. We rely heavily on our cell phones for various applications. Although the intensive use of mobile phones we were placed in a new arena, but the heart of all mobile phones have remained constant and is the battery and charge the battery. Car charger. Car chargers. Wall Chargers  all types of cell phone chargers. Fortunately. Wall chargers are the most common. These chargers are available in five varieties of base: • • • • • wall Chargers. A wall power adapter is included with your mobile phone when you buy it. emergency Chargers and green Chargers. The majority of mobile phones integrated use of batteries that can be recharged with a charger and an electrical outlet. doesn't seem to be impossible. Desktop Chargers.

Walk and charge is one of the best technologies of the battery charging ! This technology is used for charging the low – power operated devices like the mobile phone batteries, MP3 player batteries, etc. Two technologies have been tested so far to convert energy used in walking into electrical power. The first one uses piezoelectric material, which is either incorporated in discrete devices within the boot, or is an integral part of the structure of the boot. This gets compressed while you walk and generates a substantial voltage, which when combined with appropriate electronics, can be used to charge a mobile phone battery.
The other one involves placing small electro-mechanical devices, such as a dynamo, in the heel of the shoe. The dynamo spins every time your heel strikes the ground, thereby generating a small amount of current. The specialty of the walk and charge technology is that it can generate as much energy as a AA battery in 21 minutes. A 20 minute walk charges your cell phone for a day’s usage. Even if 0.1% of the Indian population uses this device, it can generate 1500 kW/h of energy and can help reduce carbon emission by 2.25 tonnes per day. Thus, Walk-N-Charge promises you a source of energy that is not only clean, portable and inexpensive, but also charges your mobile while you get charged up!
The future outlook is for the boots to generate about 1-3 W of power, so that they can power future microelectronic devices, like MP3 players, Global Positioning Systems, etc. So, here’s to a future where you can listen to music on your morning walk, or catch up with calls on your cell phone, without worrying about dying batteries. This paper also gives the additional information about the working , technical specifications and about the performance of the charger.
INTRODUCTION

Walk-n-charge is one of the technologies used to charge the low-power operated devices like mobile phone batteries, MP3 player batteries, etc while you walk!

Two technologies have been tested so far to convert energy used in walking into electrical power, and more are on the anvil. The first one uses piezoelectric material, which is either incorporated in discrete devices within the boot, or is an integral part of the structure of the boot. This gets compressed while you walk and generates a substantial voltage, which when combined with appropriate electronics, can be used to charge a mobile phone battery. The other one involves placing small electro-mechanical devices, such as a dynamo, in the heel of the shoe. The dynamo spins every time your heel strikes the ground, thereby generating a small amount of current.

The piezoelectric device generates about 150 milliwatts of power as of now, which is not sufficient to run a cell phone, but would be enough to charge the battery slowly. The dynamo technology has the potential of generating much more power than this, but the design would be more complex, and hence more costly.
