Final gyroscope design with rulers

The gyroscope project is the mid-term individual project from the course AEP 4320: MicroElectroMechanical Systems (MEMS). 

GYROSCOPE, standardized by IEEE as coriolis vibratory gyroscope (CVG) is a gyroscope that uses a vibrating structure to determine rate of rotation. CVGs are simpler and cheaper than conventional rotating gyroscopes of similar accuracy. Inexpensive CVGs manufactured with MEMS technology are widely used in smartphones, gaming devices, cameras and many other applications. In this project, the gyroscope is designed based on the following specifications.

To achieve this, I modeled and simulated my gyroscope in COMSOL, and optimized its parameters with MATLAB.
