sir,i want to create model to compare in capacitive and piezoelectric pressure sensor which is better sesor.i want to plot pressure vs voltage in both cases and want to compare it.can u please help me?

Hi

that hears like an interesting project, but before you start to model, you should perhaps try to sketch out the two solutions, define the different variables you want to play with, interfaces between the physics you intend to use and the dependent variables you need, then define the criteria you might decide to use a "juge" for the "est" solution.

Thereafter I believe it will be easier to start modelling, as you will have a better idea of which physics to use for which model, where are the"important" and dependent variables etc.

In anycase, my advice start simple one physics at a time and build your models layer by layer and physics by physcs

Good luck

thank u sir... i want to combine structural and electrostatic proerties......sir can i plot pressure vs voltage and compare...i tried ....but i got that piezoelectric pressure sensor more sensitive.....is the result is correct?
