Abstract
This work deals with the modeling of an active sensor consisting of a Josephson junction, a micro-beam immersed in a uniform magnetic field B, a dipole (r, L, C) and an auxiliary generator. In this work, an active sensor (independent of an external energy supply) capable of converting low temperature and/or a uniform magnetic field B into sinusoidal electrical voltage has been constructed. Being known as an excellent voltage-frequency converter, we have in a second time studied the influence of the Josephson junction on the oscillation frequency of the electrical and mechanical parts of the Micro Electro Mechanical System. An analytical study of the fixed points and their stability is done. On the other hand, the numerical studies have been done in order to show how the energy losses are compensated thanks to a simple rheostat of the auxiliary generator. The order
of the influence of the Josephson junction on the oscillation frequencies and the different electrodynamic modes has been obtained.
