Abstract

This paper analyzes and reports the influence of electrodes positioning on dielectric ink for the formation of stable meniscus in the electrostatic inkjet head, experimentally. To introduce the electrostatic inkjet head for the fabrication of different printed devices, it is important to know the best position of electrode in the inkjet head for the optimal electrification of the ink. The paper also examines electrode position and electrically driven liquid handling operations. From experiments, it has been deduced that the head performs best when the electrode position is at orifice in dielectric ink. For better understanding and evaluation of this phenomenon, simulations were also performed. The finite element model of the head with dielectric fluid has been developed to analyze the behavior under electric field. And to optimize the analysis, the research is also supported by the statistical techniques. Furthermore, the meniscus shape and response on applied voltage is studied and analyzed. Paper also elaborates and addresses issues like the meniscus generation using dielectric ink and ejections at low voltage with stability problems.
