When you're on the go and your smartphone battery is low, in the not-so-distant future you could charge it simply by plugging it into your shoe.
An innovative energy harvesting and storage technology developed by University of Wisconsin-Madison mechanical engineers could reduce our reliance on the batteries in our mobile devices, ensuring we have power for our devices no matter where we are.
The technology could enable a footwear-embedded energy harvester that captures energy produced by humans during walking and stores it for later use.
"Human walking carries a lot of energy," Krupenkin says. "Theoretical estimates show that it can produce up to 10 watts per shoe, and that energy is just wasted as heat. A total of 20 watts from walking is not a small thing, especially compared to the power requirements of the majority of modern mobile devices."
