NANOTECHNOLOGY NANOGENERATOR to Power Nanodevices

Introduction:
After inventing some machines which works on electricity, man tried to operate them in absence of electricity thus generator came into existence. Now the world is of nanodevices and it is time to “Nanogenerator” to come into existence. “Zhong Lin Wang”, Regents Professor in the School of Materials Science and Engineering at Georgia Tech is the initiator of this device.
Electricity Generation: to the nanogenerator, when mechanical energy such as waves or vibrations is applied, the nanowires periodically contact the tips (with the help of zigzag electrode), transferring their electrical charges. By capturing the tiny amounts of current produced by hundreds of nanowires kept in motion, the generators produce a direct current output.
The wires can be compressed, can be vibrated left or right--it doesn't matter: all the current adds up in the same direction and there will be no fear of breaking as they can bent up to 50 degrees with out breaking.
Main goal:
The main goal of them is to increase the power by some necessary makings, (as changing the coating, substrate e.t.c.,) so that it can replace the batteries and to obtain the size advantages of nanodevices.
Major hurdle: zinc oxide degrades when wet. Research is going on a process that would coat the fibers to protect the fabric in the laundry.
Few Applications:
“Our bodies are good at converting chemical energy from glucose into the mechanical energy of our muscles; these nanogenerators can take that mechanical energy and convert it to electrical energy for powering devices inside the body.
