Washington: Hate charging your cellphone every now and then? Well, a self-powering handset that never needs to be charged is on the anvil thanks to the efforts of a researcher who has developed a new technology that could make self-power devices a reality.
The self-powering cellphone won’t require its battery to be charged because it would convert sound waves produced by the user into the energy it needs to keep running.
Tahir Cagin, a professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University has used materials called “piezoelectrics” to develop self powered devices that do not require replaceable power supplies, such as batteries.
To be precise, Cagin and his partner from the University of Houston have found that a certain type of piezoelectric material when manufactured at a very small size - in this case, around 21 nanometers in thickness-can convert 100% energy. He said that when materials are made of a different size they show a decrease in their energy-converting capacity. His findings could have profound effects for low-powered devices such as mobiles and laptops.
