Abstract

The disclosure describes a z-axis gyroscope where a proof mass is suspended from a peripheral suspender and a central suspender. The peripheral suspender forms a truncated triangle around the proof mass, and the central suspender extends through the truncated corner of the triangle formed by the peripheral suspender. The proof mass is driven into a primary oscillation mode by one or more piezoelectric drive transducers located on the peripheral suspender. One or more piezoelectric sense transducers located on the base of the peripheral suspender are configured to detect the secondary oscillation mode of the proof mass.
