1) A piezoelectric accelerometer consists of a 0.1 gm mass resting on a 1mm x 1mm x0.2mm slab of PZT. (When the accelerometer is shaken, the force is applied alongthe 0.2mm dimension, which is the z axis of this crystal). The electrodes are on the1mm x 1mm sides of the piezoelectric.a) What is the sensitivity of this accelerometer?b) What is the mechanical resonant frequency of this sensor?c) Assume this piezoelectric crystal has a leakage resistance of 100 MQ. Whatis the low-frequency cut-off of this accelerometer?
