COMPREHENSIBLE MODEL OF AMPLITUDE NONLINEARITIES IN PIEZORESISTIVE-FORCE SENSORS

L. Paredes-Madrid, P. Gonzalez de Santos

Abstract

This article upgrades the RC linear model presented for the piezoresistive-force sensors. Amplitude nonlinearity was found in sensors conductance, and a characteristic equation was formulated for modeling it. By using such equation, it is possible to determine sensor sensitivity for any driving voltage below 1V. This model considerable improves the plug-and-play capability of the sensor. However, sensor conductance is unsatisfactory modeled by such equation when the input voltage goes over 1V. We present an approach for such driving condition.
