A more advanced yet sophisticated version of a pen that capable to lay down functioning electrical circuits as it draws. The brilliant idea of electrical circuits pen came from a team of researchers from University of Illinois, and it could lay down the electrical circuits owing to the silver colored ‘special’ ink that capable to turn paper, wood and other flexible surfaces.


In near future, this silver ink is going into a printer, so users could make their own circuit board by printing it out from an inkjet printer. Making thing get done in highly efficient manner while shortening the time required to build electronic circuit board through manufacturing process which requires more time, space and effort.

The initial test has shown that adding some LED lights and battery to the paper that has printed electronic circuits on it could get the lights lit up as usual.


Metallic inks have previously been used in inkjet printers to print electronic circuits, but the pen is much more mobile and can be used instantly on wide variety of surfaces at a much lower cost. The ink also maintains conductivity when folded, opening up applications in art and fashion, disposable electronics and folded, three-dimensional devices.

“Pen-based printing allows one to construct electronic devices ‘on-the-fly’, using very low cost, ubiquitous printing tools,” said Jennifer Lewis, one of the lead researchers and director of the Frederick Seitz Materials Research Laboratory at the University of Illinois.

No info when the silver ink will go for inkjet type of printer or when mass availability is possible yet.
