Future Gadgets could be charged with your Heartbeat

As the world is getting much faster and smarter with high technologies and everyone surrounded by 4G Smart phones, tablets, MP3 players, handheld gaming consoles, flashlights, health alert devices, portable laptops or think of anything that can be carried.
At the 241st National Meeting & Exposition of the American Chemical Society in Anaheim California reported success in developing nanogenerators that can produce electricity.
Dr. Zhong Lin Wang and his team of researchers at the Georgia Institute of Technology have developed tiny nanogenerators that use small movements to generate enough power.
Nanogenerators are any electric generator whose scale is measured in nanometers; they typically create electricity from the random movements of their surroundings.
This technology will provide portability for electronic products at the best level that one could ever imagine.
Nanogenerators work using zinc oxide (ZnO) nanowires -- "piezoelectric" gizmos that generates an electric current when strained or flexed.
Piezoelectricity is the ability of some materials (notably crystals and certain ceramics, including bone) to generate an electric field or electric potential in response to applied mechanical stress. So any kind of movement, walking, breathing, wind or even a Heartbeat can generate electricity.
That's great, Ur heart will soon power Ur gadgets..
The chip involved could have medicinal benefits as well, but its just an assumption and not for sure its going to happen.
Currently, these nanogenerators can power liquid-crystal displayed, LEDs, and laser diodes, scientists are looking forward to move ahead.
These nanogenerators can produce about the same voltage output as two regular AA batteries when they’re stacked five chips high.
Obviously, this much power would not be sufficient, would require more research and development.
I think one should expect at least 2-3 years for the availability of Nanogenerator technology in the market.
