A piezo accelerometer is designed with a quartz piezo disk under compression. The quartz has a dielectric

A piezo accelerometer is designed with a quartz piezo disk under compression. The quartz has a dielectric constant of 3.8, and the crystal is 2 mm in diameter and 0.15 mm thick. If the proof-mass used is 3g, what is the sensitivity of the transducer in m/s^2/V? Hint: use the definition of pressure: p = and Newton's 2nd Law F=ma with the piezo behavior of the crystal to develop an equation for the Sensitivity.
