Abstract
The present disclosure is directed to a detection structure for a vertical-axis resonant accelerometer. The detection structure includes an inertial mass suspended above a substrate and having a window provided therewithin and traversing it throughout a thickness thereof. The inertial mass is coupled to a main anchorage, arranged in the window and integral with the substrate, through a first and a second anchoring elastic element of a torsional type. The detection structure also includes at least a first resonant element having longitudinal extension, coupled between the first elastic element and a first constraint element arranged in the window. The first constraint element is suspended above the substrate, to which it is fixedly coupled through a first auxiliary anchoring element which extends below the first resonant element with longitudinal extension and is integrally coupled between the first constraint element and the main anchorage.
