Silver Filled Inkjet Printer Produces Electric Circuits

Guys from the University of Leeds found another way to use an inkjet printer – to create electric circuits.

During experiment, student Seyed Bidoki filled an HP inkjet printer with solution of silver salt and ascorbic acid, that is Vitamin C. This combination proved to be the most successful of all and included water.

"We wanted to be able to use a totally water-soluble base," said team member and chemist Matthew Clark. "That allows for much more environmentally friendly processes."

Then they printed different circuits on variety of media – paper, cotton, acetate, and even transparent film, and it worked out good. To improve conductivity, patterns are printer two or three times.

The developers say this inkjet technology has long way to go to be accepted for industrial scale production, but it does make new kind of devices possible.

This April is rich in alternative inkjet printer use. Just the other inkjet technology was used in medicine, bio engineering, nano technology research and other fields of human activities
