Researchers at the Queen Mary University of London have teamed up with Nokia to create a smartphone that is capable of charging using sound.
Nokia and the team at Queen Mary University London managed to create a prototype smartphone that is capable of charging its battery using sound, which includes everyday background noise like traffic, music and people voices.
The prototype handset is about the same size as a Nokia Lumia 925, and it generates five volts which is enough to charge the battery on the smartphone.
Dr Joe Briscoe commented: “Being able to keep mobile devices working for longer, or do away with batteries completely by tapping into the stray energy that is all around us is an exciting concept. This collaboration was an excellent opportunity to develop alternative device designs using cheap and scalable methods. We hope that we have brought this technology closer to viability.”
It certainly sounds like a very interesting idea, and if the technology can be developed further to be used in future smartphones then you may not have to ever plug your device in again to charge.
The technology could also be used for a number of other devices to charge them using sound, it will be interesting to see how it is developed.
