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.
Six authors have described their work in harvesting energy in a paper titled "Ultrathin, Rollable, Paper-Based Triboelectric Nanogenerator for Acoustic Energy Harvesting and Self-Powered Sound Recording." Translation: A paper ...
(Phys.org)—A team of researchers working at the Georgia Institute of Technology has developed a type of smart-glass that not only changes color, but creates electricity. They have published a description of their work and ...
From light-up shoes to smart watches, wearable electronics are gaining traction among consumers, but these gadgets' versatility is still held back by the stiff, short-lived batteries that are required. These limitations, ...
By analyzing such parameters as the force applied by key presses and the time interval between them, a new self-powered non-mechanical intelligent keyboard could provide a stronger layer of security for computer users. The ...
By the end of 2014, Earth will be home to more mobile electronic devices than people. Smartphones, tablets, e-readers, not to mention wearable health and fitness trackers, smart glasses and navigation devices—today's population ...
Imagine powering your cell phone by simply walking around your office or rubbing it with the palm of your hand. Rather than plugging it into the wall, you become the power source. Researchers at the 247th National Meeting ...
(Phys.org) —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 jumps from a fingertip ...
(Phys.org) —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. American researchers are now aiming to use waves ...
Researchers have discovered yet another way to harvest small amounts of electricity from motion in the world around us – this time by capturing the electrical charge produced when two different kinds of plastic materials ...
