It is very nice to use ZnO as a nanogenertaor, but why ZnO in Nanoscale, it can be used as a bulk for Piezoelectric application because D33 is low in case of nano scale ZnO.

Wouldn’t it be great if they built these Nanogenerators around springs. Then every time a spring was compressed or bounced back it would create energy. For example the springs that push the keys back up when we type on a keyboard; or the shocks in our cars.

Wristwatches have long had rotor devices to wind up their spring and/or charge their batteries – since about 40 years now!

Kids in Physical Ed classes should be required to wear a nanogenerator to recharge their cell phone or iPod batteries, while they are exercising. Or they could charge rechargeable battery packs, that could be plugged into one big central “recharger” with 20 or 30 of newly adopted Micro USB charging cords coming off of it, at the front of their classrooms. All kids would be required to place their phones on the green nano charger at the front of the classroom when they enter.

It will be interesting to see where this technology goes. The uses seem endless, sometimes the best discoveries come in small packages.

Wow! No this is what we’ve been needing! Let’s hope it doesn’t get buried by the oil companies.

This is a great development with many applications. The nanotechnology aspect of power generation is new, but harnessing mechanical energy on small scales is not. In 1770, the Swiss watchmaker Abraham-Louis Perrelet invented a self-winding mechanism in 1770 for pocket watches. This utilizes the movement of it’s wearer to wind the watch mechanism, and is still in use to this day. I guess the watchmakers of the world were the world’s first, “nanotechnologists!”

They need to put a rush on this.

Just think what kind of energy they’d make with the wind top/along the side of those skyscrapers!
