Abstract

A resonant MEMS pressure sensor in which the resonator mass of the MEMS resonator is anchored both to the fixed base beneath the resonator cavity as well as to the top membrane over the resonator cavity. This provides a more robust fixing of the resonator mass and offers a dependence of resonant frequency on the pressure outside the cavity.
