MIKROMECHANISCHER BESCHLEUNIGUNGSSENSOR
The accelerometer (ACC) has a common movable seismic element (ESMC) with movable seismic masses (MSM1, MSM2) that are displaced in translation along a sensitive axis (Oy) or in rotation with respect to a rotation axis. The masses are connected together by a flexible mechanical connection unit (OLM)...

| description | The accelerometer (ACC) has a common movable seismic element (ESMC) with movable seismic masses (MSM1, MSM2) that are displaced in translation along a sensitive axis (Oy) or in rotation with respect to a rotation axis. The masses are connected together by a flexible mechanical connection unit (OLM) i.e. flexion beam, to avoid deformation of amplification units (MA1, MA2), following the deformation of the accelerometer due to external thermal constraints. Mechanical stiffness of the connection unit is lower than that of an assembly formed by the amplification units and resonators (R1, R2). An independent claim is also included for method for thermo-mechanical decoupling of a common movable seismic element from measurement cells of a micro-machined accelerometer. |
