Sensitivity of accelerometer

Sensitivity of the accelerometer, sometimes referred to as the “scale factor” of the accelerometer, is the ratio of the sensor's electrical output to mechanical input. [Note that a transducer is defined generally as a device that converts one form of energy to another.

How do you increase the sensitivity of an accelerometer?

The sensitivity of the accelerometer is shown to increase under a large heating power. As shown in Figure 4b,c, increasing the heating power can raise the temperature difference in the cavity of the accelerometer, simultaneously providing high sensitivity.

How accurate are accelerometers?

Accelerometers can be used to make very accurate pedometers that can measure walking distance to within ±1%.

What is mV g sensitivity?

It describes the conversion between vibration and voltage at a reference frequency, such as 160 Hz. Sensitivity is specified in mV per G. If typical accelerometer sensitivity is 100 mV/G and you measure a 10 G signal, you expect a 1000 mV or 1 V output.
