Subject: [mems-talk] Piezoresistor simulation


> Hello, folks
>  I am doing piezoresistor simulation in MEMS using the program ANSYS. Do
you
> have some clues about what kind of couple-field element in Ansys can
account
> for the interaction between displacement of element ( the displacemetn
induces
> stress and stress induces strain of element then), and the change of its
> resistivity. The piezoelectric element only  reflects how structural
> displacement affect voltage distribution.
