Hi all ,(adsbygoogle = window.adsbygoogle || []).push({});

I am approaching now the piezoelectricity but I am studying economics so i have no knowledge to understand deeply some aspects of it. Anyway i am really interested in understanding it for myself.

I understood all mechanism behind it but some things are still not clear. Let's start!

1. If we use a piezoelectric surface to generate energy with a X force (N), am I getting the voltage output once or i'll get voltage output each time i apply the vertical force X?

2. In formulas terms, I used this formula to calculate the voltage output of a crystal piezoelectric surface pushed with a vertical force is :

V = [(dCan anyone confirm me this formula? I am not sure i can rely on what i get using this formula. I can say that my force is for sure vertical (approximately)._{mn}t) / (εε_{0}A)] ⋅ F_{x}

d_{mn}= piezoelectric crystal coefficient | pico-C/N

t = crystal thickness

ε = crystal dielectric coefficient

ε_{0}= 8.854 x 10^{-12}

A = area of surface

Thank you for your help.

Best,

Richard

PS. Please, excuse me if i post it in the wrong section but i couldn't classify it in other sections.
