"Power Felt" Charges Your Phone With Body Heat (And It Costs $1!)

No need to stay tethered to an electrical outlet or worry about your cellphone running out of juice; charging your smart devices could require little more than a quick jog on the spot. Scientists at Wake Forest University in North Carolina have developed a thermoelectric device that converts body heat into an electrical current. Dubbed “Power Felt,” the technology uses temperature differences —that of the room versus your body, say—to create a charge. The best part? A cellphone cover could cost as little as a buck, according to the school’s Center for Nanotechnology and Molecular Materials , which published its findings in the current issue of Nano Letters , a leading journal about nanotechnology.
