In this paper, the key stages of applying the MNM-method are represented by the example of designing the microfluidic generator of the 100-µm feature size. This is very important from the view point of the practical application, because the microfluidics is increasingly used to create high-technology products. For instance, the microfluidics provides potential to create promising non-electric reserve control systems (RCS). The prospectivity of RCS is mainly determined by the resistance of the microfluidics to multiple destabilizing factors resulting in failures of electronics (for instance, radioactive and corpuscular emissions, electromagnetic emission, high temperatures, etc.). The microfluidics has its own approaches to generating, saving, transforming, and transmitting the data. Therefore, the microfluidics allows new original cybernetic systems to be developed by means of the non-electronic element base. At the present time, the fields taking advantage of the microfluidics also are microanalytics, micromechanics, biotechnology, bioengineering and other complex scientific areas.
