Nanogenerator Produces Energy From Tires Rolling on Pavement

Researchers at the University of Wisconsin-Madison, in collaboration with a scientist in China, have developed a nanogenerator that can harvest energy from a tire rolling against the pavement . In research published in the journal Nano Energy , the international team created a single-electrode nanogenerator that could be incorporated into a tire. When the part of the tire that contains the electrode comes into contact with the pavement, the friction between the rubber and the road creates an electrical charge, which is known as the tribolectric principle . The researchers believe that capturing the energy that is typically lost in the friction between a tire and the road surface could be a new avenue for greater energy efficiency in automobiles. The researchers also determined that the amount of energy that the nanogenerator produces is proportional to the weight of the ca...
