BIOGRAPHY
Parsa Taheri received his B.S. degree in Mechanical Engineering from Sharif University of Technology in 2010. He received a MS degree in Mechanical Engineering from San Jose State University in 2012. He joined UCD MEMS Lab in 2012 under the supervision of Prof. Horsley. He is currently pursuing his PhD at UC Davis.

Micro Rate-Integrating Gyroscope [BPN603]
The goal of this project is to realize a micro rate-integrating gyroscope that
produces an output signal proportional to rotation angle rather than rotation rate. If
successful, this device would eliminate the need of integrating the gyroscope's rate
output to obtain the angle. Realizing a micro rate-integrating gyroscope can be achieved
by fabricating hemispherical resonating shells with extremely close frequency matching
(delta f < 10 Hz) and a very high quality factor (Q > 1 million). Structures must be
highly axisymmetric and micro-finished to nanometer scale roughness.
Gyroscope resonators have at least two resonant modes that can be coupled by Coriolis force.
Difference in damping coefficients and stiffness of the resonant modes of the MEMS resonator
known as anisodamping and anisoelasticity are main sources of error in RIG. Control
algorithms should be developed to eliminate these errors.
