PhD Works of Claude HUMBERT : "Coupling of  a FPGA digital filter with a QCM resonator for mass detection using mode localization"

Abstract :There is an ever growing interest in ultra-accurate mass detection in the health, environment and agri-food fields. In this context, the last two decades have seen the emergence of resonant MEMS sensors based on mode localization in an array of coupled resonators. Known to be highly sensitive to mass perturbations, this phenomenon however requires identical and weakly coupled resonators, which is a challenge due to microfabrication constraints. In order to overcome this limitation, we present in this thesis an alternative solution based on a hybrid system, where a hardware (field programmable gate array) emulating one resonator and the coupling, is connected in closed loop with a piezoelectric resonator having the interface with the particles to quantify (...).
