Impact of Ink Synthesis on Processing and Properties of Inkjet-Printed Silicon Thin Films

Drahi E., Gupta A., Blayac S., Lombez L., Jubault M., Benaben P., Ecole Nationale Supérieure des Mines de Saint Etienne, FR

Inkjet printing has a high potential for cost reduction in solar cell and thermoelectric industry. This study demonstrates that silicon thin films can be produced by inkjet-printing of a silicon ink followed by consequent drying [...]

Inkjet printing of 200 nm monodisperse carbon nanoparticles: from smart ink formulation to thin film sensor properties

Vié R., Berthon-Fabry S., Blayac S., Drahi E., Jacomet S., EMSE, FR

In this work, resorcinol / formaldehyde copolymers are pyrolyzed in order to obtain spherical monodisperse carbon nanoparticles. These particles are used to create thin films using inkjet deposition. Electrical properties of these films are, then, [...]

Ultrasonic Milling and Dispersing Technology for Inkjet Nano-Particles

Hielscher K., Hielscher Ultrasonics, DE

The application of mechanical stress – e.g. generated by ultrasonic cavitation - breaks the particle agglomerates apart. Also, liquid is pressed between the particles. Different technologies are commonly used for the dispersing of powders into [...]

Effect of Pressure Variation on Inkjet-Printed Line Pattern with Various Step Sizes of Ejected Droplets

Wang J-K, Hwang W-S, Tsai M-H, Liu Y-F, National Cheng Kung University, TW

This study investigates the effect of droplet deposition dynamics on inkjet-printed line features of deionized water using numerical analysis. Simulation results show that kinetic energy dissipation during the droplet deposition process transforms into inner wave [...]

Gravimetric calibration for optical measurements of droplets-in-flight

Verkouteren J.R., Verkouteren R.M., Zeissler C.J., Verkouteren J.R., Verkouteren R.M., National Institute of Standards and Technology, US

We report gravimetric measurements of droplets, traceable to the SI, that enable the correction and calibration of optical measurements routinely used to monitor and control the dispensing of droplets from inkjet printers. This innovation results [...]

Redesign of Magnetostrictive Inkjet PrintHead

Yoon K.H., Park Y.W., Wereley N.W., Park Y.W., Chungnam National University, KR

One of the challenges is to design a proper inkjet printhead for demanding trend. Current inkjet printheads are mostly based on either piezoelectricity or heat. This paper presents an inkjet printhead using a magnetostrictive principle. [...]

Segmented inkjet print head experiment

Einat M., Ariel University Center of Samaria, IL

Inkjet print heads are commonly designed as a device having single ink reservoir distributed to all the nozzles of the same ink. For limited number of nozzles and head size this solution works well, but [...]

Photo-induced Surface Modification of Polyimides for Printable Electronics Fablication

Yamashita T., Kodara F., Mino M., Matsuzawa Y., Okano K., Tokyo University of Science, JP

Manufacturing devices with printing technique is one of the key steps in developing printable and flexible electronics or photonics technology. But printing fine structure with ink jet technique is relatively limited because positional precision and [...]

Photocurable Composite with Antimicrobial Activity for Wound-Healing

Chang M-H, Ding F.-C., Ju W.-Y., Lai P.S., National Chung Hsing University, TW

To develop an appropriate approach that can accelerate the wound healing rate or prevent other microorganisms contamination is necessary for wound healing. In this study, the combination of antimicrobial activity and photodynamic antimicrobial chemotherapy of [...]
