Abstract

This paper mainly focuses on to get high displacement from polymer based piezoresistive cantilever for MEMS/NEMS pressure sensor applications. The displacement has been analyzed and compared with three different cantilever using PDMS (Poly dimethyl siloxane) and PMMA (Poly methyl methacrylate) materials. The p-type silicon piezoresistors connected the form based on wheat stone bridge to get high sensible pressure sensor with respect to low response. An according to get high displacement, obviously the other performance of parameters such as stress, strain gets high range. So, this analyzed cantilever structure used to design a pressure sensor with high sensitivity. The design and simulation are done by using COMSOL Multiphysics.
