Mobile Batteries Could Soon Get Powered by Your Screams
We all hate unwanted noises, whenever we are out in the public, the one thing that disturbs us the most is the sounds that we keep hearing; horns honking, babies crying, women or men fighting and so on.
What if there was a way for us to actually use the same noise to our benefit? And on top of that, what if we could use that noise to help us fix another issue that we really hate – probably even more?
Okay let me get to the point, there has been a research recently where a nanotechnology scientist has developed a product that actually gets powered by noise around it. Now you know what I was talking about, powering our gadgets (mobile batteries?) with the noise around us!
Well, they are not quite there yet, but professor Zhang Lin Wang, and a team of nano-technologists from Georgia Institute of Technology have made a microphone out of a paper that does exactly that.
What he did was that he burned tiny holes into a stamp sized paper with a laser and covered one side of the paper with copper and the other with polytetrafluoroethylene (the item used on non-sticking pans). Then, two of the sides of the paper were joined together to complete the product.
How it works is fairly simple, the waves produced by all sorts of sounds around us make vibrations in the paper based microphone and the vibrations make the two coatings go in and out of contact with each other resulting in the production of a tiny volume of electricity!
If this works, you might start liking public fights – or any sort of loud hideous sounds for that matter because who doesn’t like fully charged mobile batteries!
