Athens university prints polymer circuits with lasers, speeds us towards low-cost electronics

The dream of ubiquitous technology revolves around cheaper materials, and polymer circuits could help make the dream a reality... if the solvents used to produce the circuits didn't cause more problems than they cured, that is. The National Technical University of Athens has developed a more exacting technique that, like most good things in science, solves the crisis with lasers. The approach fires a laser at a polymer layer (covered by quartz) to throw some of that polymer on to a receiving lay...
