Abstract
This work shows the mathematical modelling of graphite piezoresistive sensor elements type 2B in paper substrate. The parameters analyzed were the sensitivity factor, variation of the electrical resistance with the applied mechanical tension (longitudinal and transversal) and piezoresistive coefficients. The results of the computational simulations were compared with the experimental data obtained through an experimental arrangement using the clamped beam method. The obtained experimental factor gauge is of the order 12 indicating that the type of graphite used is a good material for developing sensor elements.
