Piezoelectric crystal compression (in cm)

[SmritiB]

How much does a Piezoelectric crystal (say PZT) compress when applied the maximum amount of force it can withstand ? also it would be very helpful if someone could tell me how much is this force typically ?

What has your reading said so far? What information sources have you been using to read about this? What size piezo crystal are you interested in?

I have been using the internet only. Many videos on youtube show that pressing with fingers (which i presume would be around 100N force) generate 4-5V. On a piezo crstal sized around 4cm^2. What i could not get was how much distance are the pressing it. as in how much compression (in cm) can a crystal typically withstand ?
