Piezoelectric and air pressure

Click For Summary
A piezoelectric crystal in a closed circuit within a pressurized vessel may not exhibit any significant changes unless mechanical stress is applied. Air pressure can induce internal stress in the crystal, potentially generating a voltage. This principle is utilized in many pressure transducers, which convert pressure changes into electrical signals. Further details about the specific circuit and piezoelectric device are needed for a more comprehensive understanding. Overall, both mechanical stress and air pressure can influence piezoelectric behavior.

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.

Thread '3D rendering of electric field lines of a swiftly moving charge'

Happy holidays folks. So I spent some time over the Thanksgiving holidays and developed a program that renders electric field lines of swiftly moving charges according to the Liénard–Wiechert formula. The program generates static images based on the given trajectory of a charge (or multiple), and the images were compiled into a video that shows the animated field lines for harmonic movement and circular movement of a charge (or two charges). Video: The source code is available here...
