Research Claims Mobile Phones Can Be Charged Through Speech

According to the findings of a new research, the day is not far when mobile phone batteries will be charging themselves with the human voice.

The research carried out by a group of engineers in South Korea has reportedly found a way to convert sound waves, including that created by the human voice in to electricity.

According to Dr Sang-Woo Kim of Sungkyunkwan University in Seoul, the future phone batteries equipped with this technology will also be able to charge themselves from background noises, or from music even when not in use.

According to a report by the Telegraph, UK, Dr Sang-Woo Kim along with his team is currently working on the prototype of this technology which potentially can convert sound of approximately 100 decibels into 50mv of electricity.

"Sound power can be used for various novel applications including cellular phones that can be charged during conversations and sound-insulating walls near highways that generate electricity from the sound of passing vehicles," said Dr Sang-Woo Kim.

The amount, though not enough to fully charge a battery, but it will surely provide the platform where upon further improvements can be achieved, eventually leading into full functionality of the technology as desired by Dr Kim and his team, along with billions of mobile phone users all across the world.
