Formation and Modeling of Droplet Ejection for Electrohydrodynamic Inkjet Printing

Choi J., Lee S., Son S.U., Sungkyunkwan University, KR

EHD(Electrohydrodynamic) inkjet printing based on electrospray and EHD discharging for tiny droplet/jet is known to be able to generate higher resolution and higher aspect ratio of patterns than the conventional inkjet printing(Lee, 2014). EHD inkjet [...]

High Aspect Ratio EHD Printing with High Viscosity Ink Ejection

Choi J., Lee S., Kim Y.J., Son S.U., An K.C., Sungkyunkwan University, KR

EHD (Electro-hydro-dynamics) printing technology, one of the printing technologies based on EHD discharging theory, can be patterning of high resolution and high aspect ratio compared to conventional inkjet printing systems. We have been investigating to [...]

The Investigation of Electrostatic Induced Inkjet Printing System for the Ejection of a Stable Micro/Nano Droplet

Choi J., Kim Y.J., Son S.U., Chul An K., Lee S., Sungkyunkwan University, KR

Inkjet printing technology has recently attracted considerable attention for a simple fabrication and advanced pattering process during the past decade. In order to manufacture advanced inkjet printing technology, my team has alternatively proposed and investigated [...]

Electrostatic Induced Inkjet Printing System for Micro Patterning and Drop-On-Demand Jetting Characteristics

Choi J., Kim Y., Kim Y.J., Son S.U., Kim Y., Kim Y.J., Lee S., Byun D., Ko H.S., Sungkyunkwan University, KR

Printing technology is considered to be a key technology even in the field of electronics, materials processing, and bio applications. Inkjet printing is an interesting patterning technique for electronic devices because it requires no physical [...]

Pattern Characteristic by Electrostatic Drop-On-Demand Ink-jet Printing Using Capillary Inkjet Head System

Choi J., Son S.U., Kim Y., Lee S., Kim Y., Ko H.S., Byun D., Sungkyunkwan University, KR

Ink-jet printing technology is very attractive for forming micro-size patterns for flat panel displays (FPDS), semiconductor, biological and optical devices. Further the necessity of the industrial inkjet system has grown in the past years due [...]

Electrostatic Droplet Ejector with Monolithic Fabrication of Nozzle

Lee S-H., Byun D.Y., Ko H.S., Kim Y., Yang J.H., Han S.J., Son S.U., Oh J.T., Konkuk University, KR

This paper presents a novel mechanism of electrostatic micro droplet formation and ejection of fluid. Unlike conventional electrostatic jetting which requires a high operating voltage, we offer a, commercially viable, low operating voltage for droplet-on-demand [...]
