Optimal design and modeling of tactile resistive and capacitive sensors interfaces used in modern mechatronics

ABSTRACT: In one of my wider studies about the best choice of sensors that can be placed on the soles in multiple positions of the foot charge points, for real-time calibrated measuring of ground reaction forces (GRF) during human walking, has been approached the problem of optimal interfacing with the data acquisition system from tensorestive tactile sensors and one capacitive sensors. The aim of wider project was to calculate the real energetic consumption during gait as mechanical work of horizontal projection component of GRF. The paper presents the main problems and related solutions obtained by PSPICE and LAPLACE modelling and simulation. Thus, for the tactile sensors it is showed an original interfacing circuit with multiple advantages and for the capacitive sensors also an original circuit based on a capacitor-frequency converter with a linear characteristic obtained by using an equivalent negative capacitance.

KEYWORDS: PSPICE conductance model; tactile sensor interface; negative capacitance; LAPLACE analysis
