The aim of this study is to develop fabric sensors adapted to textile structure able to detect length variations, applicable to acquire biomechanical signals. To optimization of final products, controlling of production process conditions through determination of the best quality and quantity of oxidant agent using in chemical polymerization, have performed. The sensing fabric samples were prepared with in-situ deposition of Polypyrrole as electro active material on Lycra/Polyester fabric. Critical properties for characterize commercial strain gauges such as sensitivity , response time, and linearity percent , have been measured using raw data obtained from smart motor system. A range of electrical conductivity between 7.2×10 -4 to 6.9×10 -3 S/cm has been measured. According to results the maximum value of gauge factor and linearity percent belong to the samples with the highest electrical conductivity, but the best linearity percent equal to 92% belong to the samples that coating process of conductive particles on their surface have performed with no disturbance.
