Clothing Power - Innovation Nation

The video discusses the potential of piezoelectric nanofibers, which can convert mechanical energy into electrical energy. These fibers, developed at UC Berkeley with NSF support, are extremely small and can be integrated into clothing to generate power. A square millimeter of these fibers could charge a phone, but challenges remain in integrating them into devices. The Pentagon is interested in this technology for military applications, and it could offer solutions to broader energy issues.
