A new class of exotic materials could find its way into next-generation technologies that efficiently convert waste heat into electrical current according to new research.
A new electrochemical energy harvesting device can generate electrical current from the full range of human motions and is thin enough to embed in clothing.
The biological supercapacitor is a protein-based battery-like device capable of extracting energy from the human body.
Efficiency is a problem with today's solar panels; they only collect about 20 percent of available light. Now, a University of Missouri engineer has developed a flexible solar sheet that captures more than 90 percent of available light, and he plans to make prototypes available to consumers within the next five years.
(PhysOrg.com) -- Electrical engineers at the University of Michigan have built a device that can harness energy from vibrations and convert it to electricity with five to ten times greater efficiency and power than other devices in its class. And it
