Piezo crystals and current generation

Click For Summary
SUMMARY

Piezo crystals can generate electrical current when subjected to mechanical stress, such as being hit or exposed to sound. The generated current is typically very small and requires amplification for detection. By working with voltage, the minute electrical signals from piezo crystals can be amplified and subsequently converted into usable current.

PREREQUISITES
  • Understanding of piezoelectric materials
  • Basic knowledge of electrical circuits

hey

can a piezo crystal generate current when it is hit as well as when it is exposed to sound?
 
Physics news on Phys.org
It can. But it is very very small and we can't detect it simply. If we work with voltage, we can detect and amplify it after that, we can translate it to current.
