Project: Conductive Ink – How to Make Your Own

Materials researchers at the University of Illinois, Urbana-Champaign have developed a highly conductive silver ink. In this video, Analisa Russo, a graduate student in the research group of Professor Jennifer Lewis shows exactly how to make this amazing ink, which could be used for a wide variety of hobby projects and in advanced electronics hardware.

There are so many cool projects out there that use conductive ink, but where to get the ink? Now you can DIY that part, too!

Jordan Bunker of Pumping Station: One in Chicago embarked on this chemistry project and documented the UIUC process into easy-to-follow instructions.

Conductive inks have a myriad of different interesting applications. As a quick, additive construction method for electronic circuits, they are especially intriguing. Unfortunately, for a long time they have been just out of reach of the hobby market. They are too expensive to buy in decent quantities, too complicated to make, too resistive to be practical, or require high annealing temperatures (which would ruin many of the materials you’d want to put traces on).

Now, thanks to some brilliant minds at the UIUC Materials Research Laboratory, you can make your own decent conductive ink!
