Roland Piquepaille writes "A Harvard University team has successfully applied a film of nanowires on glass and plastic. This might lead to better and flexible displays or wearable computers, says the American Chemical Society, in "Nanowire film brings cheaper, faster electronics a step closer." "By using a 'bottom-up' approach pioneered by our group, which involves assembly of pre-formed nanoscale building blocks into functional devices, we can apply a film of nanowires to glass or plastics long after growth, and do so at room temperature," says Charles M. Lieber, professor of chemistry at Harvard. The researchers think that the first applications will be improved smart cards or LCD displays. But they also have a vision for the next decade. "One could imagine, for instance, contact lenses with displays and miniature computers on them, so that you can experience a virtual tour of a new city as you walk around." This overview contains more details and references. It also includes a picture of a high-density crossbar nanostructure, whose geometry can serve as the basis for many applications, like bio-sensor arrays or high-density data storage."
