A scientist Sungkyunkwan University, Seoul, South Korea, which named Dr. Sang-Woo Kim has researched and has now developed a new technology that allows mobile phone user to recharge cell phone eries by simply using the power of sound. This latest technologycan utilize axcess energy from the sound produced when a person talking on their cell phones. And the sound they make when talking with people they contact will automatically charge the mobile phone they use. We often ignore the voice that is always present in the environment and everyday life whichis one source of energy. It also motivates the researchers want to produce an energy resource by changing the sound of a person's speech, music or the sounds around into electrical energy. Sound energy can be used for various needs, including allowing for charged cell phone in the middle of a conversation and receive the sound of a running vehicle and convert it into electrical energy. Based on research, a mixture of zinc oxide between two electrodes is able to produce energy when it is vibrated by the voices arround. This study could change the sound of noisy traffic into electrical energi by 50 millivolts. That is, the concep of Dr. Kim turned out tobe proven. Now, researches have conducted a number upgrade to commercialize this product. Because this time, continued research target is to improve the composition of zinc oxide between two electrodes in order to generate more electricity than a smaller sound energy.
