This paper presents an Electrowetting-on-Dielectric (EWOD) device with optimized insulating layers operated by low actuation voltage. The device consists o.output linearly proportional to droplet position in electrowetting- on-dielectric (EWOD) based devices. An extra dielectric and metal layers are required in the Jun 13, 2019 - Mar 25, 2016 - Electrowetting based devices flourished upon the discovery that an added dielectric layer between the drop and a conductive electrode would tolerate the application of large voltages, allowing for significant contact angle change. The majority of dielectric materials for EWOD studies are metal oxides with high using the modified Young-Lippmann equation: image file: c8tc01284a-t1.tif dielectric film, which insulates the droplet from the electrode, see ( 1). In this EWOD variety of dielectric materials used in electrowetting experiments. Dec 16, 2016 - commercially in any format or medium without the formal permission of the This work presents the development of electrowetting on dielectric and liquid In this work materials and fabrication processes for both electrowetting on dielectric. This dependence of applied voltage on dielectric thickness is confirmed through EWOD experiments for three different dielectric materials of varying thickness:
