Silicon circuits that bend and stretch recently took an important step away from the world of science-fiction novels and Hollywood movies toward the real world of medical devices and media players.

A team of researchers at the University of Illinois at Urbana-Champaign (UIUC) says it has printed silicon circuits onto plastic in the form of the same CMOS circuits that dominate digital logic today. The ­breakthrough brings researchers closer to printing circuits on plastic that approach the performance and reliability of silicon chips.

Seventy-five years is a long time. It’s so long that most of us don’t remember a time before the transistor, and long enough for many engineers to have devoted entire careers to its use and development. In honor of this most important of technological achievements, this issue’s package of articles explores the transistor’s historical journey and potential future.
