Abstract
This paper describes development and characterization of fabric strain gauge sensors. In order to production of sensing
fabrics with suitable specifications, detection of the best kind and value of dopant agent using in polymerization reaction
have been performed.The composite smart products were prepared with coating process of electroactive material (Polypyrrole) on Lycra/Polyester fabric through in-situ deposiyion.Critical properties for characterize commercial strain
gauges such as sensitivity, response time and linearity percent were extracted by processing of raw data obtained from
smart motor system. A range of electrical conductivity between 2.2×10 -5
to 1.1×10 -2 S/cm have 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 93% belong to the samples that coating process of conductive particles on their surface have performed with no disturbance.
