Increased sensitivity z-axis accelerometer

Abstract:

Z-axis teeter-totter accelerometers with embedded movable structures are disclosed. The teeter-totter accelerometer may include an embedded mass which pivots or translates out-of-plane from the teeter-totter beam. The pivoting or translating embedded mass may be positioned to increase the sensitivity of the z-axis accelerometer by providing greater z-axis displacement than the teeter-totter beam itself exhibits.
