Newsoffice 2009 Nanoorigami-1-Enlarged
MIT researchers are developing what they call "nano-origami," a technique for folding materials into tiny 3D structures with edges that are a hundred times thinner than a human hair. Someday, their work could lead to minuscule motors and components for faster microprocessors. Mechanical engineering professor George Barbastathis and his colleagues pattern the 2D shapes using conventional lithography technology. Then they use an external magnetic field, a beam of helium ions, or deposit metal on the materials' surface to induce the shape to fold itself up into a 3D structure. From the MIT News Office:
The folded shapes can be fabricated with a few different types of material, including silicon, silicon nitride (a type of ceramic) and a soft polymer known as SU-8.

Once the material is folded, the tricky part is getting the faces to align properly. The researchers have developed a few ways to do this successfully: one uses magnets; another involves attaching polymers to a certain spot on the faces and melting them with an electric current, sealing the two faces together.

  1. The Future will be nanoscale. Technology will disappear. It is going to be wonderful.

    Either that or it will destroy us all. It will be fun to watch, regardless.

  2. that’s not nano! that μ symbol indicates micro. that’s micro-origami.

    yours in nano-pedantry,

  3. All this nano stuff is making me ill…

    It’s like the wave of Web 2.0! stuff before the tech sector/economy exploded….

    I can appreciate what they are doing and all the research that goes into trying to work in a nano scale environment, but…has anything useful been at least designed yet? Oh I know there are about 5 billion things that nano could make or make better…it’s like a 21st century BASF. But I want some hard built devices using nano-tech. Then I’ll shut up and be happy.
