Morph - the mobile phone of the future - A stretchable, flexible self-cleaning device that can be used as a mobile phone or keyboard that harvests solar energy and senses the environment by using nanotechnology was launched this week. [Printed Electronics News]

Carbon nanotubes have a sound future in the electronics industry - Once again transistor radios made from carbon nanotubes make the news. [Printed Electronics News]

A "nanohand" is a small gripper, small enough to manipulate nanotubes and nanofibres. This movie show how to pick and place nanofibres using a nanohand, to construct a nanodevice: a super-probe for atomic force microscopy. It takes a lot of work to get this far; and much more to get further: how about a virtual reality world where you can pick nanotubes with your own hands, while the nanogripper does it with 10000 times smaller fingers? How about an assembly line, a factory for building nanotube devices? Two big european projects, Nanorac and Nanohand, are now trying to make this reality.

A dreamy medley of nanoclips showing grippers that try to wrestle nanotubes and nanowires - watch them fight for their lives, as the "giant vice" close in for a better grip.

Topology optimisation is a powerful computerbased method for obtaining better mechanical designs... the algorithm does not care about engineer-aesthetics - yet the designs are strangely beautiful. The films shows a manipulation sequence where a carbon nanotube is broken off and transferred to a "TEM grid" - a sample suited for inspection with a Transmission Electron Microscope.

The grippers are designed and fabricated by Ozlem Sardan, MIC - Dept of Micro and Nanotechnology, Tech. Univ of Denmark. The filming and nanorobotics were done by Volkmar Eichhorn, Oldenburg University.
