What exactly is Power Felt? It is a fascinatingly new way to recharge your devices like a cellphone by the use of your body heat and a piece of this miracle material. It converts wasted body heat into electric current.
Its uses are many from powering up devices to lining automobile seats to improve battery power, or for insulating pipes or collecting heat under roof tiles to reduce gas or electric bills. It could also have monitoring applications: lining clothing or sports equipment to help determine performance, or wrapping IV or wound sites for tracking patients’ medical needs. Even the toy industry could see a big impact. Perhaps most important, you could keep it with an emergency kit for powering a cell phone, a flashlight, a weather radio. This could be crucial during power outages or after accidents.

How does it work? Power Felt is made up of tiny carbon nanotubes locked in flexible plastic fibers and made to look like fabric. It creates a charge by using temperature differences, such as room temperature versus body temperature. This principle is known as thermoelectrics – currently the subject of extensive research within the scientific community. But what if there is no significant temperature difference? Not a problem: Power Felt also has the ability to collect power from mechanical noise, any vibration that’s around it – the motion of the body or the vibration of a car.
