URBANA - CHAMPAIGN, ILLINOIS - US Scientists report that they believe they are on the way to creating a truly flexible circuit board that could be used in applications previously unavailable in PCB technology
Professor John Rogers of the University of Illinois and
colleagues have created flexible silicon and plastic circuits that are just 1.5
micrometres thick.
Researchers have reported that the boards are made of silicon "nanoribbons" and can be flexed and folded, and that circuit boards with this
type of flexibility could be used in biomedical applications.
Professor Rogers said, "The notion that silicon cannot
be used in such applications because it is intrinsically brittle and rigid has
been tossed out the window. Through carefully optimized mechanical layouts and
structural configurations, we can use silicon in integrated circuits that are
fully foldable and stretchable."
