    Abstract: A test chamber is used within a system for testing microelectromechanical systems (MEMS) pressure sensors. The system includes a processor, two air tanks pressurized to different air pressures, a high speed switch mechanism, and the test chamber. The test chamber houses a MEMS pressure sensor to be tested, a control pressure sensor, and a temperature sensor. The MEMS pressure sensor and the control pressure sensor are located in a cavity within the test chamber. The cavity is of minimal size and has a domed inner surface. A response time of the MEMS pressure sensor within the cavity can be characterized by utilizing the system and subjecting the MEMS pressure sensor to a pressure stimulus pulse produced by switching between the two air tanks.

  • Patent number: 10545167
    Abstract: Multiple-axis resonant accelerometers are based on detection of resonance frequency changes of one or more electrostatically-driven resonator masses due to electrostatic gap changes under acceleration. Specifically, one or more resonator masses are configured to resonate simultaneously in different directions associated with different axes of sensitivity (e.g., X, Y, and/or Z axes). The motion of each resonator mass is monitored through one or more electrostatically-coupled sense electrodes. An acceleration along a particular axis of sensitivity causes a small change in the electrostatic gap(s) between the corresponding resonator mass(es) and the sense electrode(s) associated with that axis of sensitivity, and this electrostatic gap change manifests as a small change in the resonance frequency of the resonator from which an accelerometer output signal can be produced.
