TO POWER NANO DEVICES
What is the necessary of NANO GENERATOR?
Materials Science research is now entered a new phase where the
structure and properties of materials are investigated, characterized
and controlled at the nano scale.
Though as sophisticated as their larger counterparts, these devices are
still burdened because they rely on an outside power.
Batteries and other traditional sources are too large, and tend to negate
the size advantages of nano devices.
To over come these challenges researches are finding alternative
ways, and nano generator is one promising answer.
A nano generator take advantage of unique coupled piezo electric &
semi conducting properties of zinc oxide nano structure (wires),
which produce small electrical charges when they are flexed.
By finding a way to collect electricity from multiple nano wires, the
researchers took a big step toward a practical nano-scale power

Researchers expect that with optimization, the nano
generator could produce as much as 4 watts per cubic
centimeter based on a calculation for a single nano wire
One day by placing these into people's shoes we can
generate electricity when walking.
Powering the simple electronic devices like BJT, FET.
The day when we can charge our cell phone or
iPod just by going for a stroll around the block
could be a step closer.
Thanks to a "nano-generator".
