Modeling and Fabrication of Low-Cost Electrowetting Actuators for Flexible Microfluidic Display Applications

Description

We investigate and characterize three different fabrication methods facilitating low-cost electrowetting on dielectric (EWOD) structures. EWOD allows setting fluid droplets in motion by electrically altering the surface tension equilibrium at the triple contact line. We present a fabrication method for flexible EWOD structures by screen printing a transparent and conducting poly (3, 4-ethylenedioxythiophene) polystyrene sulfonate (PDOT:PSS) polymer on polyethylene terephthalate (PET) foil. As a demonstator for applications, a prototype of a flexible microfluidic EWOD display cell is FEM simulated and characterized in terms of feasibility and response speed for various pixel scalings. The accordingly constructed microfluidic pixel serves as a basis cell for a future flexible EWOD cell multigrid where all pixels are directly addressable.
