Scientist use household product to fuel sound wave advancement.

Voice calls may be the key to a longer battery life for cell phones.  A group of Korean scientists are now working on a way to power up cell phone batteries with just a little conversation.  

Researchers Young Jun Park and Sang-Woo Kim led the team who discovered how to utilize the prime ingredient in calamine lotion -- zinc oxide --  to develop a nanomaterial that turns sound waves into electricity.

After creating a field of nanowires sandwiched between two electrodes, the group was able to produce a current of 50 millivolts by blasting the field with sound waves of 100db (a normal conversation is 60-70db), according to 
Syberplanet.net.

"Just as speakers transform electric signals into sound, the opposite process — of turning sound into a source of electrical power — is possible. 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," said Young Jun Park and Sang-Woo Kim.

In addition to the possibility of using this research to help keep phones charged in the future, the technology is also being considered as a means to add power to electrical grids during rush hour.

Young Jun Park and Sang-Woo Kim presented their findings in an article which appears in the 
 Advanced Materials journal.
