Piezoelectric Accelerometer

Piezoelectric accelerometers are widely used for vibration measurements due to their low cost and very wide frequency range for which the
sensitivity is constant. The resonance frequency is very high (∼10 kHz).
However, because they do not respond to low frequency accelerations, they are not suitable for use in, for example, inertial navigation
systems. Such applications need accelerometers that respond down to zero frequency - e.g. the servo accelerometer.
