The structure we study is composed in stacking alternate layers of Silica and Tungsten and presents a torsional resonant mode which presents a high quality factor and a high mass sensitivity, in a case of a homogeneous perturbation. In a case of a non-homogeneous mass-perturbation over the pillars, each pillar gives a contribution to the signal perturbation under the form of a shifted peak. These results show that each pillar gives a contribution to the output signal and that the high quality factor of the structure allows to distinguishing the different perturbations.Show less >
