origami technique to create three-dimensional mikroustroystva 
origami technique to create three-dimensional mikroustroystva   Origami - technique of folding paper figures - with the competent approach allows you to create unique objects. By no less dramatic results may result nanorigami, when carried out the formation of three-dimensional microstructures of the tiny elements by bending the latter. Similar mikrokonstruktsii can create tiny motors, capacitors next generation, and in the future it will help create mikroorigami storage device, chips, photonic mikroustroystva with unique characteristics.
The main advantage of the new approach is the possibility of forming three-dimensional microobjects - so far engineers have learned to create complex two-dimensional structure, using techniques such as photolithography, the technology nanopechati, etc. It is suitable for the manufacture of integrated circuits and MEMS-devices, they are totally unsuitable for creating three-dimensional nanosystems.
This technique nanoorigami to help engineers in creating new types of electronic devices, even more so that the first successes in this direction already exist. The staff of Technology University of Massachusetts presented his vision for creating technology 3D-objects:first using traditional technologies, such as lithography, a next scan device, and then, by bending the petals and a ready-capable device. In 2005, members of MIT provided the public the first three-dimensional capacitor, designed to accommodate the formation of a single fold. The next stage of technology development has been to explore the possibility of a second petal, located perpendicular to the first. In this case significantly increases the capacity of your device.
However, the main problem that faces today`s researchers, the challenge is how to make the material curve, with the desired angle and in the right direction. At the moment, considered several options:the deposition of metal (eg, chromium) on the surface of a bend that makes the material intertwine, but in this case is difficult to achieve the desired angle and the correct form of a bend. Bending the material beam of helium ions - this method allows you to bend the material in the right direction, and angle of bend can be adjusted by changing the energy of ions. The bend of the material through the formation of most thin wires of gold, which then affect the external magnetic field.
What is interesting, technology nanoorigami employments as in the case of silicon, silicon nitride (ceramic type), and polymers. This makes it applicable to the materials with different physical and electrical properties, allowing you to create virtually any type of microdevices.
