Ionic-liquid-based gel electrolyte boosts flexible supercapacitors

A newly developed ionic-liquid- and silica-based gel electrolyte greatly improves both the energy and power density of flexible supercapacitors, say researchers at Korea University.

Implanted biofuel cell converts bug's chemistry into electricity

An insect's internal chemicals can be converted to electricity, potentially providing power for sensors, recording devices or to control the bug, a group of researchers at Case Western Reserve University report.

Battery that can be woven into clothing

Researchers at the Polytechnic School of Montreal in Canada have built a battery that can be woven into a garment.

Solar cells from grass clippings

Within a few years, people in remote villages in the developing world may be able to make their own solar panels, at low cost, using otherwise worthless agricultural waste as their raw material.

Pacemaker powered by heartbeats

Aerospace engineers from the University of Michigan in Ann Arbor have developed a prototype device that could power a pacemaker using vibrations in the chest cavity that are due mainly to heartbeats.
