Abstract :
Due to their pliability, sensitivity and cheapness, piezoresistive sensors can be usefully adopted to recover joint bend angles in human body movement tracking. After providing quasi-static and dynamic electrical characterization of piezoresistive sensors, the authors develop a simple and accurate RLC model fitted on sensor electrical response under fast deformation and relaxation movements, which allows to predict the actual device behavior in tracking body fast movements.
