Pen Makers Electric Circuits

There is a new way to create electrical circuits that could be the key to creating a disposable electronic devices. You can make it by writing with a tool like a pen.

Scientists from the Illinois University has developed a silver-inked pen Rolerball who can put an electric circuit connected with the surface of paper, wood, and other surfaces. Jennifer Lewis, professor of materials science and engineering said that the pen that can print the electrical circuit allows one to build electronic devices "on the fly". "This is an important step which allows desktop manufacturing progress (personal fabrication), using a very low cost and use any printing device," said Lewis added. The ink pen is a real solution. After writing, the liquid in the ink will dry and leave a conductive silver lines. In essence, such as paper attached with wire. Maintain the conductivity of the ink, but the paper will fold and bend. This allows the device to be very flexible. "The main advantage of this pen is no need to use a printhead printers that cost is quite expensive, but can be replaced with less expensive equipment and can be grasped as a tool for writing," says Lewis.*** [TG Daily | jam | PIKIRAN RAKYAT 21072011]
