Abstract:
A gyroscope comprising: a multi-layer substrate, comprising drive spring and sense spring layers; a rigid support structure formed from the substrate; a plurality of drive springs formed in each drive spring layer wherein each drive spring is operatively coupled to the support structure; a drive mass formed from at least one layer of the substrate, wherein the drive mass is coupled to the support structure via the drive springs; a drive mass driver operatively coupled to the drive mass and configured to cause movement of the drive mass with respect to the support structure; a plurality of sense springs formed in each sense spring layer, wherein each sense spring is operatively coupled to the drive mass; and a sense mass formed from at least one layer, wherein the sense mass is coupled to the drive mass via the sense springs.
