In addition to successfully harvesting energy from each of its components simultaneously, the device is also extremely compact, with a height of several hundred nanometers. This means it can fit in some of the smallest devices designed for ultra-low power that are beginning to leverage different types of harvesters rather than use batteries for power.

Hybrid energy harvesters can be used in festivals for lighting LEDs decorative. Well festivals means lot of noise where piezoelectric nanogenerators are exposed to sound.

Live music is likely to exceed 100db, in fact I've seen soundmen "tune" the system to produce 120db at the stage, but in normal city noise 100db would be quite alot of racket.

Elizabeth, this is a great application of technologies to provide low power harvested from the environment.  While this is a very efficient way to do it, one one chip, it might be easier to put several technologies together in a package that integrates them.

Good point, tekochip. Rock concerts have been known to hit 120 dB, as you point out. This would be a great source of energy at a daytime rock cocert.

Ahan great this is very interesting and usefull technology.Will the sound of vehicles on the roads and sound of birds in the enviornment will also be able to harvest energy .If yes then this will be a very usefull technology

I am sure we are talking about very small amounts of energy, but it doesn't take much to run the newest components.  A very good idea, as ambient noise and light is present almost everywhere.

I completely agree with all the comments that this is a good idea, and I especially like this festival idea. Not only is there a lot of sound fibration at festivals, but usually they're held in good weather, so the solar aspect of the harvester also could be used. I think it would be great if we all had one of these with us to augment our power supplies when we need to from the environment.

Hi, naperlou...not sure what you mean exactly by this? Can you explain a bit? Thanks!

As I mentioned elsewhere, cars would also be a natural for harvesting energy from vibration. Even the interior of most vehicles offers that potential.

Indeed, Chuck, cars would be a great source of vibration energy, particularly the engine. Do you know of any hybrid or electric car makers working on this, or any other research? I'd be surprised if there wasn't something in the works.
