Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which MEMS devices senses a change in an object’s inertia sometimes by utilizing a suspended mass.
A
Pressure sensors
B
Chemical sensors
C
Intertial sensors
D
Transistors
Explanation: 

Detailed explanation-1: -MEMS inertial sensors are designed to sense a change in an object’s inertia, to convert, or transduce inertial force into a measurable signal. 9 They measure changes in acceleration, vibration, orientation and inclination. This is done through the use of micro-sized devices called accelerometers and gyroscopes.

Detailed explanation-2: -Often the inertial sensors are supplemented by a barometric altimeter and sometimes by magnetic sensors (magnetometers) and/or speed measuring devices. INSs are used on mobile robots and on vehicles such as ships, aircraft, submarines, guided missiles, and spacecraft.

Detailed explanation-3: -Gyroscopes are inertial sensors measuring angular motion about one or several axes. As acceleration is proportional to external force, this measurement can reflect both the intensity and frequency of human movement.

Detailed explanation-4: -Crash sensing for air bag control represents the largest automotive use of inertial MEMS sensors. In this application, an accelerometer continuously measures the acceleration of the car.

Detailed explanation-5: -Noise. There are many contributors to noise in an accelerometer-the sensor itself, the readout electronics, mechanical damping, and all electrical resistances. Examples. High-g Accelerometers. Angular Accelerometers. Geophones. Tuning Fork Gyroscopes. Vibrating-Wheel Gyroscopes. Wine Glass Resonator Gyroscopes. More items
