The course is focused on the theory of the proposal electromechanical systems, which allows the exact proposal movement members at the micro and nano dimensions. Focused on detail the effects of electromagnetic fields in a defined tangible environment and the corresponding motion equation, characterizing the linear and rotary motion in this environment. Mechanical behavior of the system is transferred to the analogous behavior of electrical circuits using a mathematical model of the circuit. The theory also notes possible implementation of logic functions AND and OR-based polymer chains. The theory seeks to practical rules of the draft movement members, at least one geometric dimension is the nanoměřítka, ie from 1 nanometre to 100 nanometres.
