Solid-gap wine-glass mode disks VB-FET resonators applied to biomass sensing
We simulate with FEM a VB-FET resonator to improve the output signal. HfO2 solid-gap is expected to improve the Q-factor and reduce Rx. Frequency shift due to position and contact area of attached mass is studied. Frequency shift due to disk geometry is studied. Point and distributed mass sensitivities are calculated.
