Description
Summary:[Display omitted] •Mathematical modeling of the electro-mechanical system.•Studies of fixed points and their stabilities.•Control of amplitudes and oscillation frequencies with different types of Josephson junctions.•Highlighting chaotic, pseudo-periodic and periodic oscillation modes. This paper deals with a technique for modeling the frequency, amplitudes and electro-dynamic modes of a NEMS (Nano Electro-Mechanical System) obtained by coupling two resonators at a Josephson junction. After a mathematical modeling of the electromechanical system, we firstly illustrated the fixed points and their conditions of stability. A numerical study illustrates how one could simultaneously increase the frequency and amplitude of vibration of the nanobeam using different types of Josephson junctions. On the other hand, we have shown various types of applications that this NEMS could have in particular its efficiency in cryogenic conditions to serve as a passive temperature sensor.
