Piezoelectric crystal compression (in cm)

Click For Summary
SUMMARY

The discussion centers on the compression characteristics of Piezoelectric crystals, specifically PZT (Lead Zirconate Titanate). It is established that applying a force of approximately 100N to a 4cm² PZT crystal can generate a voltage of 4-5V. However, the exact compression distance in centimeters that such a crystal can withstand under maximum force remains unclear, with participants seeking specific measurements and data sources to clarify this aspect.

PREREQUISITES
  • Understanding of piezoelectric materials and their properties
  • Knowledge of force measurement units (Newtons)
  • Familiarity with voltage generation in piezoelectric systems

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 ?
