Description
Summary:Magnetoelastic resonant platforms are gaining attention in different sensing applications due mainly to their wireless detecting capacity. In that way, the improvement of the main parameters of those devices turns out to be essential in the development of advanced functional magnetoelastic resonators. In our attempt to improve such systems, we concluded that modified geometries of the resonant platforms can be a good alternative to achieve higher mass sensitivities. In this work, a novel high sensitive rhombus shaped magnetoelastic resonant platform design has been proposed. The obtained mass sensitivities have been both experimentally and theoretically compared with the classical rectangular sensors case. The results of these novel sensor geometry performance show an increase on the resonance frequency value by a factor of 1.53 with respect to the traditional rectangular one and, as a first consequence, an improvement of more than a 60 % in the mass sensitivity value. Besides, a multiple detection system based on a combination of both magnetoelastic platform geometries has been developed. The obtained results are very promising in the goal of achieving improved and novel multiple detection systems.
