Carbon Nanotube-enabled "Power Felt" Could Eventually Power Your Cell Phone
Researchers at the Wake Forest University Center for Nanotechnology and Molecular Materials have developed an inexpensive thermoelectric material that could be a solution for powering small electronic devices, like cell phones.The new material can convert differences in temperature into electrical energy more efficiently and inexpensively than existing solutions.

As reported in the journal Nano Letters, the material is a thin film made from a combination of multi-walled carbon nanotubes and polyvinylidene fluoride. While carbon nanotube/polymer composites are known to exhibit thermoelectric effects, the researchers discovered that they could generate more voltage by layering the film: the thermoelectric voltage generated was the sum of contributions from each layer, which considerably boosted the thermoelectric conversion efficiency.
