I am having a structure(2D/3D) consisting of metallic conductor embedded in a polymer, I want to observe the resistance change due to initial strain in the strain matrix,I am observing that changing strain is not having any impact on the resistiance, although I have mentioned the conductor as a piezoresistive material,does anyone have any reference on how to move forward

Load Cell Design Using COMSOL Multiphysics

Abstract—COMSOL Multiphysics was used to
design a binocular load cell. A three-dimensional
linear solid model of the load cell spring element
was studied to quantify the high-strain regions under
loading conditions. The load cell was fabricated from
6061 aluminum, and general purpose Constantin alloy
strain gages were installed at the four high-strain
regions of the spring element. The four gages were
wired as a full Wheatstone bridge configuration and
total strain was measured for applied loads ranging
from 0-2.5 kg in 100 g increments. Model total strain
was measured using point probes at each of the four
strain locations, and with a load parametric analysis.
Absolute mean model-predicted strain was 1.41% of
measured strain. The load cell was highly linear, with
correlation coefficient r2=0.9999.
