Nanowire “inks” enable paper-based printable electronics

By suspending metal nanoparticles in liquids, scientists are brewing up conductive ink-jet printer “inks” to print inexpensive, customizable circuit patterns on just about any surface.
Printed electronics currently have one major drawback: for the circuits to work, they first have to be heated to melt all the nanoparticles together into a single conductive wire, making it impossible to print circuits on inexpensive plastics or paper. A new study by Duke researchers shows that tweaking the shape of the nanoparticles in the ink might just eliminate the need for heat. An article about the research is published in ACS Applied Materials and Interfaces (News Item Duke University, 3 January 2017).
