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.
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.
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
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.
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.
Using wireless chips and accessories, engineers can now extract data from the unlikeliest of places -- pumps, motors, bridges, conveyors, refineries, cooling towers, parking garages, down-hole drills and just about anything else that can benefit from monitoring.
With strong marketplace demand for qualified engineers across the board that currently outstrips the available supply, there may never be a better time for engineers and project managers to advance their careers and salaries. Whether those moves are successful in the short-term and long-term is likely to depend on how the transition from one job to the next is handled.
