Newest Energy Scavenging Approach

For quite a while the idea of powering mobile device using energy harvesting has been around.
The main problem with this so far has been the small power that could be generated with these harvesting circuits.
Some researchers have now presented a new approach that might make this more feasible in the future. It is based on piezoelectric zinc-oxide nanowires aound 2-3 um in diameter.
Due to their small dimensions these nanowires promise a power generation per volume significantly higher than achieved with current techniques.
