New Concepts of Modeling and Complex Simulation of Electronic Circuits for Interfacing Tactile Sensors in Cyber-mechatronic Systems

Abstract

Abstract The paper presents an original concept for interfacing tactile force sensors in modern cyber-mechatronic systems. The authors show the results and conclusions of a PSPICE simulation of an original patented circuit. In the simulations, in models used were introduced some circuit components corresponding to the physical implementation for a practical mechatronic system which has already been used for the analysis of human walking. After these simulations were revealed important aspects of dynamic behavior and was proposed an optimal variant of the interface circuit as a non-typically instrumentation differential circuit spitted in two parts, one near to the sensor, and the second far from the sensor and close to an A/D converter of the data acquisition system. For electrical links between the two parts can be used low cost cable without important loss of the signal / noise ratio.
