Circuit Scribe Conductive Silver Ink Pen

Circuit Scribe Conductive Silver Ink Pen: Draw Circuits Instantly

Silver pen or silver ink circuit pen can write electric circuits and interconnects directly onto paper and other surfaces.

People have been using pens to write down your thoughts for thousands of years, but now engineers at the University of Illinois have developed a roller-tinted silver pen that allows users to write down electrical circuits and interconnects on paper, wood and other surfaces . Looking like a normal ballpoint pen, ink pen is a real silver solution that dries to leave silver conductive pathways electricity. These pathways maintain their conductivity through multiple bends and folds the paper, allowing users to make personally inexpensive, flexible and disposable devices.

While metallic inks have been used for the manufacture of electronic devices using printing technology inkjet, silver pen gives users the freedom and flexibility to build electronic devices on the go, says Jennifer Lewis, Professor Hans Thurnauer of materials science and engineering at the University of Illinois who led the research team, along with Jennifer Bernhard, a professor of electrical and computer engineering.

"The main advantage of the Circuit Scribe Conductive Silver Ink Pen is that the costly printers and printheads typically required for inkjet or other printing methods are replaced with a writing tool inexpensive hand," Lewis said. "This is an important step in enabling desktop manufacturing (or personal fabrication) with a very low cost, printing tools everywhere."

Researchers have used the pen to create a flexible LED display on paper, conductive three-dimensional text and radio frequency antennas. Now they plan to expand the palette of inks to enable writing pencil on paper other electronic materials and ionically conductive.

While the pen is more likely to appeal to electrical engineers and hobbyists, researchers have also highlighted the device's potential to create art. Using the pen to draw a copy of the painting "Sae-Han-Do" by Jung Hee Kim, who portrays a house, trees and Chinese text, the researchers used the ink as wiring for an LED mounted on the ceiling the house that was powered by a five-volt battery connected to the edge of the painting.

The research team at the University of Illinois appears in the journal Advanced Materials .

My Rating 4/5
Review:Used this to repair a damaged ribbon cable that connected my dishwasher's control panel to the controller board. This pen saved me upwards to few hundred dollars on the restoration of control panel. conductivity is excellent. Minus one star for flexibility though: once this dries it appears quite prone to cracking
