Abstract

Flexible electrodes are crucial for the growth of modern flexible electronics or smart clothing. Their ability to serve as sensing elements, deliver energy or transmit electrical signals in different conditions is essential for the evolution of wearables that will enrich our everyday life. In this study, we focus our efforts on understanding the impact of an additional protective layer on elongated and washed roll-to-roll printed (R2R) conductive flexible electrodes of various shapes. The electrical and morphological examinations provide information on the performance of the electrodes and materials during washing and elongation cycles. The acquired results indicate propitious electrode shapes as well as data concerning micro-scale cracking mechanisms, which are responsible for electrode performance degradation. The application of commercially available pastes and R2R printing methods allow the flawless utilization of the results and the fabrication of flexible and more reliable electronic components.
