A New Step to Powering Lights and Charging Batteries

Researchers at UW-Madison have discovered an inexpensive, simple way to convert footsteps into usable electricity. The method, published in Nano Energy, uses chemically treated cellulose nanofibers from wood pulp that, when in contact with untreated nanofibers in flooring, create an electrical charge set off by footsteps. Because wood pulp is an abundant waste material, this technology could make electricity generating flooring cost competitive with conventional flooring. Read more.
