One of the biggest problems mobile phone users face is running out of battery at the most crucial of moments, but scientist from Korea have come up with an ingenious solutions which sees sounds waves being converted into energy. That means you can charge while you chat.

With the popularity of versatile smartphones which carry out a number of tasks, rapid battery consumption which causes your phone to die in less than 12 hours is an annoyance and many people want to recycle mobile phones and buy one with a better battery life as a result.

Using the main ingredient in calamine lotion, the ointment used to calm itches and skin irritations, it is turned into a tiny material which converts sound waves into electricity.

"Just as speakers transform electric signals into sound, the opposite process — of turning sound into a source of electrical power — is possible," said Young Jun Park and Sang-Woo Kim, the two corresponding authors of a new article in the journal Advanced Materials.

"Sound power can be used for various novel applications including mobile phones that can be charged during conversations and sound-insulating walls near highways that generate electricity from the sound of passing vehicles," the co-authors added.

It could mean that having a phone conversation could charge your handset, or even the noise of a traffic jam or loud concert. Using energy like this could save money on phone charging electric bills.
