Summary: The demand for flexible electronic devices has increased due to the high interest in electronic textiles (e-textiles). This has led to a growing interest in flexible energy storage devices to power e-textiles. This study introduces the use of electrospray deposition (ESD) technique for depositing PEDOT:PSS on conductive carbon yarns, creating flexible electrodes with a high surface area. The optimized deposition conditions of PEDOT:PSS have been evaluated for its electrochemical performance in a 1D symmetric supercapacitor with a cellulose-based gel as an electrolyte and separator, showing high specific capacitance, excellent cyclability, and outstanding bending capability.
