Can Piezoelectric Materials Produce Current Only When Bent One Way?

Click For Summary
SUMMARY

Piezoelectric materials generate electric charge when mechanically stressed, producing voltage in response to bending. They exhibit directional behavior, moving one way under positive voltage and the opposite under negative voltage. The discussion highlights that piezoelectric materials do not produce current in a conventional sense but rather generate voltage. Additionally, the arrangement of piezoelectric elements on a substrate can affect their performance by reducing stress when bent in certain directions.

Is there a type of piezoelectric material that only produces a current when bent one way or only bends one way when applied a current?
 
Engineering news on Phys.org
Piezoelectric materials generate electric charge (voltage) when stressed/flexed. They move in one direction when a positive voltage is applied and in the other direction when a negative voltage is applied.

Nowhere in the above statements can you find the term "current".

Read about it here: (and the references at the bottom)

I imagine if you had the piezoelectric material mounted on a substrate. And it was segregated. then when you bent it to be convex, the piezo electric elements would have gaps in between it and thus be under significantly less stress.
