Gyroscope
A gyroscope is a device to measure angular orientation and angular velocity. Traditionally it was a spinning wheel mounted on three gimbals.
Modern simpler devices make use of the coriolis effect and use vibrating structures instead of a rotating one.
MEMS Gyroscope
A mems gyroscope makes use of a vibrating structure instead of a rotating structure, which makes it much simpler to manufacture.
A drive frame (yellow) is oscillated (usually at 10-40kHz).
When the sensor is rotated, the red mass is moved to either side and thus reducing/increasing the contacts to the blue sensing structure. See How MEMS Accelerometer Gyroscope Magnetometer Work & Arduino Tutorial - YouTube for more details.
