  4. Abstract:
  5. Transparent electrowetting is a branch of Electrowetting on Dielectric (EWOD) devices that use transparent electrodes. These devices are often utilized for optical applications like liquid lenses and reflective displays. In this paper, for the first time, a transparent EWOD with permanent liquid electrodes is introduced. A conductive solution was used as electrodes instead of conventional solid-state ones. We study the speed of droplets in both the proposed design and a similar conventional Printed Circuit Board (PCB) EWOD. The concept of Liquid Electrode EWOD (LEWOD) is successfully implemented on both rigid and flexible substrates. Our results generally show a promising performance similar to the PCBs, which indicates that liquid electrodes can also be used in many applications of EWOD systems in future. © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature
