MEMS Gyroscopes

  1. Apr 18, 2013 #1
    I have a basic question about MEMS gyros -

    Let's say a dual axis(X & Y) gyro IC is lying flat. Ideally the output reading would be zero.
    If I lift one end of the IC by some degrees, there would be change in output reading. Let's call this new reading.
    When the IC is held at this position, would the reading be zero or still show new reading.

    MEMS gyros are some form of VSG in a single package.

    My understanding was: rotating produces an acceleration due to the coriolis effect which changes the form of the vibrations. When you stop rotating, the force stops, and the vibrations maintain their last form. It is the form of the vibration (details depending on the method used) that tells you the tilt angle.
