abstract = "We have developed a deposition method that enhances charge delivery of screen printed electrodes by up to six times through electrochemical deposition of poly (3,4-ethylenedioxythiophene):p-toluenesulfonate (PEDOT-PTS). In order to elucidate the effects of PEDOT-PTS deposition on the long-term electrochemical characterization of screen-printed electrodes we characterized electrode stability with cyclic voltammetry and impedance spectroscopy at room temperature and at 47 °C. A deposition current of 0.4 mA/cm2 guarantees coverage of the working electrode conductive area with no spill of the conductive polymer through the insulating tracks. Control electrodes show charge storage capacity of 0.25 mC. PEDOT-PTS deposited electrodes are stable for over 4 months and present cathodic charge storage capacity of 1.25 mC.",
