Electrowetting on dielectric: liquid device abrication and multiphysics simulation

Electrowetting on dielectric (EWOD) is the change in weatability due to an applied electrostatic field. This effect is nowadays used to electrostatically control the shape of a liquid [1], developing the so-called liquid lenses (e.g. Varioptic [2]) or liquid pixels (e.g. Amazon Liquavista [3]) light...

In this work, a reliable and simple microfabrication process for EWOD displays and mirrors has been developed. Such a process ensures repeatability, compatibility with current TFT technology and scalability. Furthermore, realistic finite element multiphysics simulations of pixel structures have been developed. These models helped to understand how the switching phenomenon occurs. The main fabrication problems lie in the hydrophobic film treatment and the pixel filling. As a consequence, special attention was taken in these critical aspects. A novel non-coherent UV surface treatment for thin polymer films was investigated using contact angle measurements, SEM images and XPS measurements. Unlike the treatments existing in the literature, the results show that the treatment does not introduce any physical damage to the hydrophobic layer. Concerning the pixel filling method a ?Self-Assembly Oil?Water Perfusion? was implemented which dramatically reduce the filling complexity.Universitat Politècnica de CatalunyaBermejo Broto, Sandra20182018-07-0120182018-11-17master thesishttp://purl.org/coar/resource_type/c_bdccNAhttp://purl.org/coar/version/c_be7fb7dd8ff6fe43info:eu-repo/semantics/masterThesisapplication/pdfhttps://hdl.handle.net/2117/124609reponame:UPCommons.
