Keywords: MEMS, gyroscope, Allan variance, stability, bias, random walk 1 INTRODUCTION The rate gyroscope output is disturbed by two main groups of errors. The first group represents deterministic errors like a constant bias or a nonlinearity. These errors can be corrected by the calibration
The mechanical response of MEMS inertial sensors (accelerometers and gyros) must be tested to verify the mechanical integrity and performance of the sensor element. One major obstacle to identifying inertial sensor defects early in the manufacturing process has been an inability to dynamically stimulate and sense the mechanical performance of the sensor at wafer level.
gyroscope, together with the most fundamental nonidealities, are described, a short introduction to various manufacturingtechnologies is given, and a brief review of pub lished microgyroscopes and of commercial microgyroscopes is provided.
MEMS gyroscopes operate in the conventional mode [8] where movement of themass along drive axis is relatively large and the movement along the sense axis is very small.
For the mechanical engineers: the sensitivity of MEMS gyroscopes is usually in mV/dps (or degrees per second), so the output of the oscillator (in mV) divided by the sensitivity (mV/dps) provides the angular rate applied to the package, in degrees per second.
MEMS Inertial and Pressure Sensors Microelectromechanical system (MEMS) sensors, including accelerometers, gyroscopes, pressure sensors, and microphones, have become a multibillion dollar market in consumer electronics, automobile, and industrial applications.
The lumped mechanical model of a zaxis MEMS gyroscope is presented in Figure order to analyze dynamics of the vibratory gyroscope and derive equations of motion, two righthanded Cartesian reference frames are considered.

A vibrating structure gyroscope, defined by the IEEE as a Coriolis vibratory gyroscope (CVG), is a gyroscope that uses a vibrating structure to determine the rate of rotation. A vibrating structure gyroscope functions much like the halteres of flies ( insects in the order Diptera ).
Students in engineering sciences from the third year on should be able to benefit from this description. The most important mechanical sensors are described and discussed in detail with respect to fabrication issues, function and performance. Special emphasis is given to pressure sensors, force sensors, accelerometers, gyroscopes and flow sensors.
A MEMS (microelectricalmechanical system) gyroscope is a device that is used for measuring orientation. Accelerometers can perform a similar function when they are stationary by measuring the components on each axis of Earth's gravitational field.
