This paper focuses on development and characterization of fabric strain gauge sensors were used to detect biomechanical signals.Finally,sensing fabrics produced with suitable specifications in form smart textiles. The optimization of production process have performed with detection of the best pre-treatment conditions. The composite smart material and structures were prepared using Polypyrrole-1,5 naphthalene disulphonic acid as conductive electro active material on Lycra/Polyester fabric substrate through chemical oxidation deposition. Sensing fabric samples were characterized based on standard tests available for commercial strain gauges. Critical properties like sensitivity, response time and linearity were extracted according to raw data obtained from smart motor system. A range of electrical conductivity between 4.3×10-5 to 4.8×10-3 S/cm have been measured for samples prepared with different pre-treatment process. Results show that the samples have highest Gauge factor and lowest response time are the same as the samples with the maximum of electrical conductivity; and The Maximum value of linearity specifically was obtained for samples with homogenous distribution of nanoparticle entire fabric surface .
