Piezoresistive Beam

Please login with a confirmed email address before reporting spam

Does anyone here uses Piezoresitive module for modeling a piezoresistive beam? Or has any example which s/he can send for me?
I am really confused about the results and I need to take a look at one example.


When I model a beam with Si3N4 and P doped silicon in Electromechanical module I get reasonable value for deflection but in this module I can not measure change on current (or resistance due to deflection)
When I model the same beam in Piezoresistive module the deflection is far beyond reasonable values (like 10^8 more!!)
I have no idea what is the problem.

It's been 3 years but I would really like to know about your piezoresistive beam.
I want to design a beam and place 4 piezoresistors on it in a wheatstone bridge connection.

Any help?
