It seems that everyone is hell-bent on solving the smartphone battery dilemma since it's emerged that it's actually nice, once in a while, to be able to call people.
Researchers at Nokia and Queen Mary University in London have come up with a novel idea to attack the problem - harvesting sound and everyday noise to charge your phone. Cool.
The concept of harvesting sound and converting it to electricity has been around for about 20 years - it's made possible by the use of zinc oxide, which produces electrical currents from mechanical stress thanks to its piezoelectric properties.
"it would also be helpful to the environment — if we can use even a small amount of the waste energy (light, heat, sound, movement)"
One of the chief researchers, Joe Briscoe, told Mashable that "charging by sound and vibrations could help improve the usability of electronic devices and allow them to work for longer, without worrying about connecting to a charger...it would also be helpful to the environment — if we can use even a small amount of the waste energy (light, heat, sound, movement) in the environment, we can reduce the need for conventional electricity produced from fossil fuels."
While this sounds very promising, it's not something to scream about just yet. The smartphone is still in prototype phase and we might have to wait a couple of years to see this development hit the consumer market.
