Lightweight Wearable Tech Transforms Body Heat into Electricity

Imagine a future where working up a sweat not only does your body good, but it’ll also keep your favorite devices humming. That’s the goal of researchers at North Carolina State University , where Daryoosh Vashaee and his team have developed a way to harvest body heat and turn it into electricity. Although similar technologies have been around for years, NC State said that its prototypes are lightweight, flexes to the body, and generate “far more” electricity than their predecessors. “Wearable thermoelectric generators generate electricity by making use of the temperature differential between your body and the ambient air,” Vashaee, an associate professor of electrical and computer engineering, and the corresponding author of a paper on the work, explained. “Previous approaches either made use of heat sinks—which are heavy, stiff and bulky—or were able to generate only one...
