"A new way of making ultrathin, flexible and transparent electronics has been unveiled by researchers in Switzerland," reports Physics World. "The technique involves fabricating micron-thick electronic devices on a conventional silicon wafer, which is later detached by soaking it in water. The free-floating devices can then be placed onto a variety of biological tissues, including human skin and even a single hair. The technology could be used to make "smart" contact lenses for monitoring the pressure in an eyeball or for creating flexible solar cells." Read more.
