Preparation and Analysis of Nano materials for Smart textile in Continuous Monitoring of Physiological Parameters

Abstract

Smart textiles are the textiles used for their extended features, such as, antibacterial, flame retardancy, UV protection, anti-static, water repelling and electro-conductivity. In this paper, wearable textile-based electrodes for physiological measurement has been proposed. The fabric based conductive material used in the textile electrode provides comfort to the user. For making the fabric conductive, PEDOT:PSS solution has been used. Together with it, silver nanoparticles and copper nanoparticles were blended for better conductivity. For preparation of silver and copper nanoparticles, a reduction approach using sodium borohydride was done. The synthesized copper and silver nanoparticles were found to be highly pure with no Silver or Copper oxide on the surface. Silver nanoparticles are very good at absorbing light. The synthesis of silver nano particles was done using the chemical reduction method of Silver Nitrate by Sodium Borohydride whereas for copper nanoparticles, reduction method was done using Sodium Borohydride. The particle aggregation of silver nanoparticles was prevented by the addition of Sodium Lauryl Sulphate. Further, they were coated on the fabric and then validated with various tests.
