Harvesting Electricity: Triboelectric Generators Capture Wasted Power

submitted by: nsf

With one stomp of his foot, Zhong Lin Wang illuminates a thousand LED bulbs--with no batteries or power cord. A professor at the Georgia Institute of Technology, Wang is using what’s technically known as the triboelectric effect to create surprising amounts of electric power by rubbing or touching two different materials together.

Graphene and Mobile Ions: The Key to All-Plastic, Solution-Processed Light-Emitting Devices

submitted by: NateRobinson
The emerging field of “organic” or “plastic” electronics has brought low-voltage, ultrathin, and energy-efficient lighting and displays to market as organic light-emitting diode (OLED) televisions and displays in cameras and mobile phones. Despite using carbon-based materials as the light-emitting layer, previous efficient organic electronic light-emitting devices have required at least one metal electrode. Here, we utilize chemically derived graphene for the transparent cathode in...
