Scientists from the University of Illinois have developed a silver-ink roller-ball pen that allows users to draw electric circuits and interconnects with it on various materials such as paper, wood, tile and other surfaces that don’t conduct electricity.

Jennifer A. Lewis, the Hans Thurnauer Professor of Materials Science, said that the pen allows for a lot of potential for designing cheap and temporary circuits for various applications, because people are no longer confined to using silver ink jet printers to produce electrical circuits. Also, circuits can be drawn pretty much around any corner and crevice, allowing for connections in the oddest of places.

While the Silver Ink pen is a great achievement for the scientists, they are now developing inks for other purposes within the field of electrical conductivity.

On another note, artists have picked up the tool for other purposes including creating LED signs on office paper, and much more. For instance the scientists traced a painting called “Sae-Han-Do” originally painted by Jung Hee Kim. They used the ink to attach an LED to the top of the house, as seen in the picture below.

You can read up the entire publication in the latest issue of Advanced Materials by Wiley.
