Design of Inkjet Printing Head, Based on Electrowetting Effect, for Printable Electronics Applications

In this paper we have designed a FEM model of an electrowetting based printing head. The design and simulation were made taking into account the requirements of the new field "printable electronics". For computational modelling, coventor CFD and Ansys FLOTRAN, CFX and multiple Cosolver were used. The computed results show that the designed principle has good resolution, high aspect ratio, fast printing speed and high accuracy in droplet placement
