Efficiency of a system at any stage of its evolution can be improved by transition from a macrolevel to a microlevel: a microlevel substance capable of delivering the required function when interacting with a field replaces the system or its part.

Notes: There is multitude of microlevel states of a substance (crystal lattice, molecules, ions, domains, atoms, fundamental particles, fields, etc.). Therefore, various options of transition to a microlevel and various options of transition from one microlevel to another, lower one, should be considered when solving a problem.

Example: Instead of a micro screw, a microscopic table can be positioned by fixing it on a metal rod that is subjected to a thermal field. The rod expands and contracts relatively the value of the temperature due to the effect of thermal expansion.
