Micro Patterning of Organic Solvents on OLED Device Using EHD Inkjet Technology

Lee S-H., Nguyen X.H., Jo W., Ko H.S., Sungkyunkwan University, KR

Although there are many modes of the ejection mechanism from the EHD nozzle [2], a cone-jet mode, a pulse-jet mode and a micro-dripping mode have been analyzed by capturing the jetting phenomena using organic solvents [...]

Expanding Capabilities of a Machine Vision System for Analysis of Drops-in-flight

Kipman Y., Mehta P., Wang S-W., ImageXpert Inc., US

Measuring in-flight characteristics of ink drops under different conditions can provide insight into relationships and interactions, helping drive system and consumable optimization for manufacturers of inkjet heads, head driver electronics, inks, and integrated printing and [...]

New developments in inkjet of deposits carried out under localised extraction or helium

Conedera V., Mesnilgrente F., Fadel P., Fabre N., LAAS/CNRS, FR

In inkjet, inks used are based on aqueous or organic solvents. Solvents with low boiling point present the drawback of drying quickly and then we can observe the clogging of the orifices of ink jet [...]

Machine Vision System for Analysis of Drops-in-flight and Wetting Visualization

Kipman Y., ImageXpert Inc., US

An integrated, machine-vision system, JetXpert, has been developed for the visualization of faceplate wetting and the measurement of drops-in-flight. For print head wetting, the system uses a camera and light source set at an angle [...]

Inkjet Printed Devices for Armament Applications

Zunino III J.L., Schmidt D.P., Petrock A.M., Fuchs B.E., U.S. Army, US

U.S. Army Armaments Research Development and Engineering Center (ARDEC) is developing the capability to custom design, manufacture and integrate novel technologies into functional devices for the creation and advancement of active systems, including printed electronics, [...]

Rapid Metallization of Silver and Copper Nano Inks by Surface Wave Plasma Sintering

Cho J-M, Lee Y.I., Song Y.A., Kim D-H., Kim S.E., Kim T-H., Kim D-H., Kim S.E., Kim T-H., Kim D-H., Kim S.E., Kim T-H., Samsung Electro-mechanics Co. Ltd., KR

Inkjet printing technique of nano-sized silver or copper particles currently has had lots of attention as an alternative to conventional lithography and etching process for electronic devices in view of reducing costs. The inkjet-printed nano [...]

Printed sensor and liquid actuation on natural fiber based substrate

Saarinen J.J., Ihalainen P., Määttänen A., Bollström R., Peltonen J., Abo Akademi University, FI

Recently we have developed a new biobased substrate for printed functionality that, compared to the conventional plastic films, is recyclable and renewable based on natural fibers. Inkjet printed transistor functionality has already been realized and [...]

Drop Formation and Control of Non-Newtonian Fluid

Gao J., Ng K., Eastman Kodak Company, US

It is well known that fluid jets tend to break up into droplets of multiple sizes. However, the ability to make and control individual droplets from arrays of such jets in speed, number, and size [...]

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, [...]

Jet-printed Si nanowires for flexible backplane applications

Wong W.S., Raychaudhuri S., Sambandan S., Lujan R., Street R.A., Palo Alto Research Center, US

The integration of Si nanowire (Si NW) materials with low-temperature plastic substrates can enhance the performance of low-cost flexible electronics. We report the properties of Si NW field-effect transistors (FETs) fabricated with various contact metals [...]
