Use of electric energy stored in a textile-based PEDOT:PSS capacitor

Flexible capacitors were made using stainless steel yarns as yarn electrodes on textile substrate. The electrolyte material used was a dispersion of polyethylene dioxythiophene (PEDOT) : polystyrene sulphonate (PSS). After charging the capacitor for sufficient time, a sharp voltage drop was observed initially for a few seconds, then the voltage discharge slows down. It was not easy to establish the energy stored in the capacitor due to the self-discharge, however the capacitor could be used to power a TOSHIBA LC-810 calculator for 37. seconds
