Scientists in North Carolina have recently developed a felt-like fabric that generates power by scavenging for so-called waste heat, such as body heat.
Right now, many of the electronic devices we use every day, such as cellphones or laptop computers, get their power from batteries.
But, as we also know, even the best batteries eventually run low on power and need to be recharged.
What the Wake Forest University scientists have done is develop technology that takes your body heat, along with other waste heat, and convert it to electrical energy.
Developed at the university’s Center for Nanotechnology and Molecular Materials, the material is made up of carbon nanotubes, tiny tube-shaped materials made of carbon, which are held in flexible plastic fibers and made to feel like fabric.
The researchers say the thermoelectric technology behind Power Felt uses differences in temperature, such as room temperature versus body temperature, to create an electrical charge.
