Printable silicon for ultrahigh performance flexible electronic systems

By carving specks of single crystal silicon from a bulk wafer and casting them onto sheets of plastic, scientists at the University of Illinois at Urbana-Champaign have demonstrated a route to ultrahigh performance, mechanically flexible thin-film transistors. The process could enable new applications in consumer electronics – such as inexpensive wall-to-wall displays and intelligent but disposable radio frequency identification tags – and could even be used in applications that require significant computing power.
