Ever cell phone user finds it annoying when the battery suddenly goes dead without warning. You may not have to face this harsh reality in the future. Researchers have come up with a way by which body heat can be turned into electricity, this means individuals will be able charge their devices on the go in case of emergencies. Through touch, Power Felt can increase the battery life of a cell phone by 20%. Credit for this technology goes to David Carroll a professor at Wake Forest University Center for Nanotechnology and Molecular Materials, US.
Carroll and his team used nanotechnology concepts to insert minute carbon nanotubes into plastic fibers (miniscule) giving it the look of a small piece of fabric. While offering an explanation on how the mechanism works Carroll said” If you grab one end of a bar of metal, the electrons that heat your hand become warm. As they warm, they seek out the cold spots, which could be the other end of the bar.
So (the electrons go) rushing down to the other end of the bar. So I have excess of electrons on one side, and a depletion of excess electrons underneath my hands, so I have voltage between the two which is called thermal voltage. And that’s what Power Felt generates”. Flexible technology is going to be used excessively to charge devices in future.
