INTRODUCTION Scientists from the Georgia Institute of Technology in the US, made their discovery using zinc oxide nanowires which produce electricity whenever they are stretched. Any body movement, even the pinch of a finger, could be used to generate power. This technology will soon be used to charge mobile using heart beat.

NANO CHIP Each chip is made up of millions of nano wires, which are so small that 500 could fit in a human hair. Nanowires and more Nano generators, stacked together produce enough energy for powering larger electronics, such as an iPod or charging a cell phone.

WORKING Whenever the heart produces beats, the nanochip present over the chest receives the frequency of vibration of heartbeat. Due to this disturbance in the surroundings of nano chip, the nano wires inside the chip stresses. As a result it produces electricity which is stored inside the chip for charging gadgets

ADVANTAGES  Easy to charge.  power saving.  no need of external batteries.  less cost.  more efficient.  time consumption.

DISADVANTAGE The problem with humans is that they really don't move around that much at the kind of frequency needed to generate a sufficient amount of electricity.

APPLICATIONS  In pace makers.  In iPods and mobile phones.  Also in wrist watches.  For walky talky phones.

CONCLUSION The plan is to use the human heart to power the devices such as iPods, mobile phones by eliminating batteries. This technology will soon be used to recharge mobiles. These are very useful for real life human beings.
