  • DUAL-SEALED ACCELEROMETER WITH CAVITY PRESSURE MONITORING
    Publication number: 20240183877
    Abstract: A MEMS accelerometer package includes multiple cavities such that a change in pressure corresponding to a breach in one or more of the cavities is readily identified based on the output of a pressure-sensitive sensor such as a MEMS resonator. One or more mitigations may be initiated in response to the identification of the change in pressure.

  • Piezoresistive detection resonant device in particular with large vibration amplitude
    Patent number: 11125632
    Abstract: Piezoresistive detection resonant device comprising a substrate, a mobile par configured to move with respect the substrate, suspension elements suspending the mobile part to the substrate, a piezoresistive detection device to detect the motions of the mobile part, said piezoresistive detection device comprising at least one strain gauge, wherein the piezoresistive detection resonant device also comprises a folded spring with at least two spring arms, connected to the mobile part and configured to be deformed by the motion of the mobile part, the at least one gauge being suspended between the substrate and the folded spring in such manner that the deformation of the gauge is reduced compared to the motion of the mobile part.
