Soon, electronic device that can become invisible

Washington: Scientists in California, US, have developed tiny electronic circuits that could pave the way for transparent electronics and other futuristic applications, including flexible electronic newspapers and wearable clothing displays.
In the new study, Chongwu Zhou and colleagues point out that although scientists have previously developed nano-sized transparent circuits, previous versions are limited to a handful of materials that are transparent semiconductors.
The researchers describe the development of transparent thin-film transistors (TTFTs) composed of highly aligned, single-walled carbon nanotubes - each about 1/50,000th the width of a single human hair.
They are transparent, flexible, and perform well.
Laboratory experiments showed that TTFTs could be easily applied to glass and plastic surfaces, and showed promise in other ways for a range of possible practical applications.
This research is a significant advance toward the long-sought goal of "invisible electronics" and transparent displays, which can be highly desirable for heads-up displays, wind-shield displays, and electronic paper.
