(Nanowerk News) Never get stranded with a dead cell phone again. A promising new nanotechnology called Power Felt, a thermoelectric device that converts body heat into an electrical current, soon could create enough juice to make another call simply by touching it.
Developed by researchers in the Center for Nanotechnology and Molecular Materials at Wake Forest University, Power Felt is comprised of tiny carbon nanotubes locked up in flexible plastic fibers and made to feel like fabric. The technology uses temperature differences – room temperature versus body temperature, for instance – to create a charge.
