Now Can In-Charge Phone with Voice?


NEW YORK - A South Korean scientists find new technology that allows mobile phone users to recharge its battery just by using the power of voice. Waahh ...?

Is Dr. Sang-Woo Kim, a researcher at Sungkyunkwan University in Seoul, who developed the technology. This technology can utilize excess energy from the sound produced by a person when talking on their cell phone to charge the device.

"The voice that is always present in the environment and everyday life we are often overlooked as a source of energy. This motivates us to produce energy resources by changing the sound of someone talking, music or the sounds around into electrical energy," said Kim was quoted as saying Cellular News, on Monday (05/09/2011).

"sound energy can be used for various needs, including allowing the phone to in-charge in the middle of a conversation and receive sound from a running vehicle and convert it into electrical energy,"continued Kim.

Based on the research of Kim, a mixture of zinc oxide between two electrodes capable of producing energy when vibrated by the sounds around. Research prototype is able to change the sound of noisy traffic into electrical energy by 50 millivolts.

That is, the concept of Dr. Kim was able to prove. Now, Dr. Kim and his research team have to do some upgrades to commercialize this product.

Currently, the target of continued research of Dr. Kim is to improve the composition of zinc oxide between two electrodes in order to generate more electricity than a smaller sound energy.
