Graphene electrode was printed on textile substrate in-plane symmetrical shape using manual screen printer and dried for 10 minutes under 80 °C. The PVA gel electrolyte was developed by dissolving polyvinyl alcohol (PVA) in an aqueous solution of H2SO4 (50 g/L). The solution was stirred constantly at room temperature for 60 minutes and then heated to 80 °C with continues stirrer 500 to 700 rpm till produce a clear solution. A 1.5 ml volume of PVA gel electrolyte was drop casted over the graphene electrode and dried before being wrapped with very flexible and transparent single-sided adhesive tape.
