Abstract Scope |
Magnetoelastic sensors are becoming an interesting sensing technology because, besides exhibiting a fast response and be very cheap, they present a wireless sensing capacity. Despite their potentials, the improve of their sensitivity and selectivity is a key. This work explores the functionalization of magnetoelastic resonators with porous MOFs active layers to endows them with high adsorption capacity and selectivity. Different MOF materials and different functionalizations process are explored. In particular, the performance of a rhombic resonator functionalized with a high-toluene adsorption capacity MOF (UiO66-NH2) is explored for its wireless detection. Results confirm the feasibility of the system for fast, reversible and selective toluene detection, being key the control of the active layer mass as well as the resonator geometry. Given the structural diversity of MOs, their use as active layers in magnetoelastic systems opens plenty of possibilities for the future design of wireless sensors for different hazardous substances. |
