Xerox Corp. (http://rbi.ims.ca/3849-537) has developed a new semiconductive ink and other new materials that may make printing complete plastic transistor circuits possible. Xerox says the new ink can be used to print the semiconductor channels of transistors at low temperature and in open air—a feature that's critical for low-cost manufacturing, as the electrical properties of most liquid-processable organic semiconductors degrade when exposed to atmospheric oxygen, making it difficult to build functional transistors.
Fifty-six-year-old Pasquale Russo has been doing metalwork for more than 30 years in a tiny southern Italy village. Many craftsmen like him brought with them fabrication skills when they came from the Old World to America.
