Repeated Duplication in EHD Line Patterning on a Non-Conductive Substrate Based on Controlling the Polarity of Applied Voltages

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

This paper addresses the EHD printing of a high aspect ratio of metal lines as a means of forming a high conductivity of metal lines. As stated earlier, EHD printing is advantageous over conventional inkjet [...]

FineMetalLine Patterning on Hydrophilic Non-Conductive SubstratesBased on EHD Printing withLaser Sintering

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

In this paper, we report the successful EHD printing and laser sintering of a 5 um width of metal line patterns, with the line thickness of over 340 nm, on a hydrophilic non-conductive glass substrate [...]

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 [...]

Array-Nozzle EHD Print Head and its Drop-on-Demand Experimentation

Son S., Lee S., Lee W.H., Kim Y.J., An K., Choi J., Sin J., Lee S., Lee W.H., Wijesundara M., Stephanou H.E., Sungkyunkwan University, KR

EHD (electrohydrodynamics) printing has recently attracted attention for micro/nano size pattern devices due to it can make very small droplet than nozzle diameter and possibility of the use of various ink such as including metal, [...]

Study of the phenomenon of meniscus deformation and ejection by pulse voltage and frequency in drop-on-demand EHD printing

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

EHD (electrohydrodynamics) printing has recently attracted attention for micro/nano size pattern devices due to it can make very small droplet than nozzle diameter and possibility of the use of various ink such as including metal, [...]
