What is a MEMS Rate Gyroscope?
There are many forms of gyroscopes but inside of the Wii MotionPlus, there are chips that are used to measure the rate of rotation along all 3-axes of X (pitch), Y (roll), and Z (yaw). Inside the chip’s packages are Micro-Electromechanical systems (MEMS) that senses the user’s rotational movements with the Wii MotionPlus equipped remote.
