MEMS (Silicon Ring)
• Silicon Ring Resonator
– 3mm overall diameter, 65µm thick
– Eight pairs of ‘dog-leg’ support spokes
– DRIE bulk silicon process – no small gaps leading to risk
of stiction
– Excited into a ‘Cos2θ’ vibration mode at 22kHz
– Innovative spoke design for greatly reduced quad bias
variation. Inherently good bias over temperature
– Shock and vibration insensitive due to balanced ring
design (not a simple ‘tuning fork’)
• Strain Film Transducers
– Transducer segments bonded onto Si ring periphery
– Low noise output
– Drives: Bending moment excites Cos2θ operation
– Pickoffs: EMF output in response to strain input
– Four secondary pick-offs for maximum signal:noise

Cos2θVibration Mode at 22kHz
This shows the ring when powered and
vibrating in its elliptical mode about the
primary axes
In this view the gyro is not rotating and
therefore the nodes on the secondary axes (at 45°) are
effectively stationary.
