    Abstract: A capacitive pressure sensor (100) includes a substrate wafer (114) and a diaphragm wafer (112). The substrate wafer defines a substrate recess (R") with a first depth (D2). The diaphragm wafer defines a diaphragm recess (R"') with a second depth (D3). The diaphragm wafer is bonded to the substrate wafer such that the substrate and diaphragm recesses form a height differentiated pressure chamber (126).

    Abstract: A system for determining in-plane acceleration of an object. The system includes an in-plane accelerometer with a substrate rigidly attached to an object, and a proof mass-formed from a single piece of material-movably positioned a predetermined distance above the substrate. The proof mass includes a plurality of electrode protrusions extending downward from the proof mass to form a gap of varying height between the proof mass and the substrate. The proof mass is configured to move in a direction parallel to the upper surfaces of each of the plurality of substrate electrodes when the object is accelerating, which results in a change in the area of the gap, and a change in capacitance between the substrate and the proof mass. The in-plane accelerometer can be fabricated using the same techniques used to fabricate an out-of-plane accelerometer and is suitable for high-shock applications.
