US start-up to produce silver ink for drawing circuits

Two former academics are developing a silver conductive ink that could make designing circuits as easy as drawing a picture with a pen. Through their start-up company, Electroninks, the researchers are planning to cash in on the commercial viability of the ink, developed during their time at the University of Illinois.

The circuit scribe pen can write in conductive inkThe pair is using online crowdsourcing via Kickstarter to secure backing for Electroninks, and such has been the enthusiasm that it has quickly exceeded its investment target of $85,000 (€62,000).

To make the technology as easy as possible to use, the ink is being made available in a rollerball pen, Circuit Scribe. It is designed to integrate fully with existing development hardware like Makey Makey and Audrino. Electroninks believes the product will find multiple uses in areas such as education.

Electroninks has several development projects in the pipeline, including allowing the ink to be deposited using an inkjet printer and a second pen that would allow resistors to be drawn into ink circuits.
