Engineers at Duke University have developed the world s first fully recyclable printed electronics. By demonstrating a crucial and relatively complex computer component the transistor created with three carbon-based inks, the researchers hope to inspire a new generation of recyclable electronics to help fight the growing global epidemic of electronic waste.
The work appears online April 26 in the journal Nature Electronics.
Silicon-based computer components are probably never going away, and we don t expect easily recyclable electronics like ours to replace the technology and devices that are already widely used, said Aaron Franklin, the Addy Professor of Electrical and Computer Engineering at Duke.

Soft robotic dragonfly detects environmental conditions in water

Engineers at Duke University developed an entirely soft robot shaped like a dragonfly designed to skim across the water’s surface and react to environmental conditions. The robot, called DraBot, is entirely electronics-free and reacts to environmental conditions like pH, temperature, or the presence of oil. Researchers believe that the proof of principle demonstration unit could be the precursor to a more advanced autonomous and long-range environmental robot able to monitor for a range of issues.
Researchers on the project began by designing a soft robot based on a fly. After several iterations, researchers settled on the shape of a dragonfly engineered with a network of interior micro-channels allowing it to be controlled via air pressure. The body of the robot is about 2.25 inches long with a 1.4-inch wingspan.
