A group of University of Wisconsin-Madison engineers and a collaborator from China have developed a nanogenerator that harvests energy from a car’s rolling tire friction. An innovative... Read more
With one stomp of his foot, Zhong Lin Wang illuminates a thousand LED bulbs – with no batteries or power cord. The current comes from essentially the same source as that tiny spark that jump... Read more
The Triboelectric Effect As sources of renewable energy, sun and wind have one major disadvantage: it isn’t always sunny or windy. Waves in the ocean, on the other hand, are never still. Ame... Read more
“We are combining our earlier nanogenerator and this new triboelectric generator for complementary purposes.” Triboelectric Generator Produces Electricity by Harnessing Frictional Forc... Read more
