Silver Pen Allows For Hand-Written Circuits 161
Zothecula writes "People have been using pens to jot down their thoughts for thousands of years but now engineers at the University of Illinois have developed a silver-inked rollerball pen that allows users to jot down electrical circuits and interconnects on paper, wood and other surfaces. Looking just like a regular ballpoint pen, the pen's ink consists of a solution of real silver that dries to leave electrically conductive silver pathways. These pathways maintain their conductivity through multiple bends and folds of the paper, enabling users to personally fabricate low-cost, flexible and disposable electronic devices."

This is not really new stuff... Silver pens for "circuit repair" have been available for ages... They made a ballpoint version.

They didn't claim to invent the fucking paper too
as others have pointed out this has been around for decades, and you can make your own ghetto version using copper radiator repair solution
