Engineers Create Gel Pens That Draw Working Circuits

Engineers Create Gel Pens That Draw Working Circuits

Imagine doodling about in your Moleskin, throwing some batteries and LEDs onto the page and having your sketches illuminated like a Christmas light arrangement. Swapping the metallic ink of gel pens for real silver can make that a reality.

University of Illinois engineers have pioneered circuit pens, rendering wires unnecessary. The silver drawn by the pens naturally conducts electricity, so the only materials needed for makeshift circuits are a power source (batteries) and outputs (LEDs). If the idea of paper-and-ink as a circuit sounds rather undependable, the UI researchers bent the drawn-on paper 6,000 times before the ink began to crack. Thus, the pens are not only easier and cheaper to use, they seem to be a sturdier option for circuit-building, too.

Ravers rejoice—the possibilities are endless.
