Electrical treeing represents a critical degradation mechanism in high voltage insulation systems, often leading to premature failure of polymeric materials. This phenomenon involves the progressive ...

It's true. Scientists know that each individual tree generates a faint (we're talking 100 to 200 millivolts) electrical current. Recently, however, researchers have begun to figure out why and ...

You've probably already heard of the idea of harvesting electricity from body heat to power small devices, such as those in the far-flung idea of a body area network. Now, a similar idea has been ...
