Redesign of Magnetostrictive Inkjet PrintHead
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. [...]
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 [...]
Effect of Pressure Variation on Inkjet-Printed Line Pattern with Various Step Sizes of Ejected Droplets
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 [...]
Ultrasonic Milling and Dispersing Technology for Inkjet Nano-Particles
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 [...]
Inkjet printing of 200 nm monodisperse carbon nanoparticles: from smart ink formulation to thin film sensor properties
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, [...]
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 [...]
Effects of Poly-(N-vinyl-2-pyrrolidone) Additive on Direct-Inkjet-Printed Silver Nitrate Conductive Lines
All-printed electronics has attracted attention due to their fast processing and low cost. Inkjet printing allows circuit components to be directly drawn at a specific area in one step. The printed patterns can be used [...]
Effects of Inkjet Printing Parameters on Conductive Line Patterns for Flexible Electronics Applications
Aqueous silver nitrate ink (5 moles/liter) mixed with poly(N-vinyl-2-pyrrolidone) (PVP) was employed in a piezoelectric inkjet printing apparatus to construct conductive patterns on ultraviolet/O3-treated polyimide substrates. At a pulse amplitude of ±38 V, single droplets [...]
Bioprinting Technology for Regenerative Medicine Applications
Advances in micro- and nano-scale processing technologies have provided various therapeutic opportunities in the field of medicine. While techniques developed for tissue engineering and regenerative medicine applications have had initial successes in building a number [...]
Bio-ink for inkjet printing of living cells
Ferris C.J., Gilmore K.J., Beirne S., McCallum D., Wallace G.G., in het Panhuis M., ARC Centre of Excellence for Electromaterials Science (ACES), AU
This abstract summarises our recent work on the development of a bio-ink tailored for the controlled deposition of cells by inkjet printing. Direct printing of living cells is an emerging approach to the fabrication of [...]
Ink-jet Printed CdS Thin Film Transistors Fabricated In-situ by Micro-reaction
Ramos J.C., Kabir D., Mejia J.I., Martinez C.A., Quevedo-Lopez M.A., University of Texas at Dallas, US
Printed electronics has become a promising technology due to its lithography and vacuum-free processing. However, several issues remain unsolved: most printable semiconductors nowadays are organic molecules with low mobilities and poor air and moisture stability. [...]
A Study of Molten Lead-Free Solder Deposited by Inkjet Printing for Interconnections of Thin-Film Solar Cell Modules
Solar cell modules generally are bonded with photovoltaic ribbon using silver paste to increase photovoltaic conversion efficiency. However, the joint strength of silver paste between the aluminum back electrode and the ribbon may be the [...]
