“Power Felt” turns body heat into electricity

Is there anything that carbon nanotubes can’t do?

“When graduate student Corey Hewitt (Ph.D. ’13) touches a two-inch square of black fabric, a meter goes berserk.

Simply by touching a small piece of Power Felt – a promising new thermoelectric device developed by team of researchers in the Center for Nanotechnology and Molecular Materials – he has converted his body heat into an electrical current.

Comprised of tiny carbon nanotubes locked up in flexible plastic fibers and made to feel like fabric, Power Felt uses temperature differences – room temperature versus body temperature, for instance – to create a charge.”

Many objects and surfaces around us throw off significant waste heat – and this material could capture it for re-use – the possibilities are nearly limitless. It’s exciting developments like this that convince me our future will be bright – despite all the ticks and mosquitos that are constantly trying to suck our freedom and energies away from us.
