Piezoelectric and air pressure

Click For Summary
SUMMARY

The discussion centers on the behavior of piezoelectric crystals within a closed circuit in a pressurized vessel. It is established that while mechanical stress is a primary factor in generating piezoelectric voltage, air pressure can also induce internal stress, thereby producing voltage. This principle is utilized in pressure transducers, which convert pressure changes into electrical signals. The conversation emphasizes the need for clarity regarding the specific type of piezoelectric device and circuit configuration involved.

I was just wondering if anyone could explain to me what would happen to a piezoelectric crystal on a closed circuit in a pressurised vessel?

Near as I can tell, nothing at all. Can you provide more detail about what you are trying to do and what you think is happening? What kind of circuit? What kind of piezoelectric device?
 
I think he wants to know if only mechanical stress can cause a piezoelectric voltage, or if air pressure can do it also.
 
If air pressure causes an internal stress, then it can certainly cause a voltage. This is how many pressure transducers work.
