“The idea of using wood to generate energy is usually associated with directly combusting wood to produce heat. But a University of Maryland-led team of researchers has created a heat-to-electricity device that runs on ions and which could someday harness the body’s heat to provide energy.

A team comprising Liangbing Hu, Robert Briber and Tian Li, all of the University of Maryland’s department of materials science, and Siddhartha Das of the department of mechanical engineering, transformed a piece of wood into a flexible membrane that generates energy from the same type of electric current (ions) that the human body runs on. This energy is generated using charged channel walls and…”
