Open Image…Save ImageOpen Image (using #TmpD/ia)… University of Waterloo engineers have created a new material that converts the simple mechanical vibrations all around us into electricity. The applications run from sensors in everything from pacemakers to spacecraft. The first of its kind and the product of a decade of work in the piezoelectric effect by researchers at the University of […]

Tiny Triboelectric Generators Get an Upgrade
January 14, 2016 | Leave a Comment
Georgia Institute of Technology scientists announced a two-stage power management and storage system could dramatically improve the efficiency of triboelectric generators. Triboelectric generators harvest energy from irregular human motion such as walking, running or finger tapping. The system uses a small capacitor to capture alternating current generated by the biomechanical activity. When the first capacitor […]

Harvesting Energy From Tire Friction
June 30, 2015 | 1 Comment
University of Wisconsin-Madison engineers and a collaborator from China have developed a nanogenerator that harvests energy from a car tire’s rolling friction. Xudong Wang, the Harvey D. Spangler fellow and an associate professor of materials science and engineering at UW-Madison, and his PhD student Yanchao Mao have been working on this device for about a […]
