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 [...]

Modeling Drop Generation at the Microscale

Hanchak M.S., Furlani E.P., Eastman Kodak Company, US

In this presentation a numerical model is described for predicting drop generation from microscale liquid jets of Newtonian fluid. The model uses a one-dimensional slender-jet approximation to obtain the equations of motion for the free-surface [...]

Manipulating Optical Properties of Luminescent Nanoparticle Substrates through Inkjet Printing

Guzan K., Sumerel J., Davis L., Hoertz P., Mills K., Magnus-Aryitey D., RTI International, US

In this work, an ink jet printer has been used to deposit patterns of photoluminescent particles onto nanofiber substrates allowing control of correlated color temperature (CCT) and color rendering index (CRI) of the resultant photoluminescent [...]

A Finite Element Analysis for a Supercritical Particulate Process

Bakhbakhi Y., King Saud University, SA

Nonconventional processing methods can lead to the development of materials with unique chemical, physical or mechanical characteristics that make them suitable for specialized applications. One such method is crystallization with supercritical fluids (SCFs), where the [...]

Applied Systems and Synthetic Biology in Micro-Fluidic Biochips

Zeng B.J., Benjoe Institute of Systems Bioengineering, CN

The design of bio-molecular systems within cells, it is a recently achievement of synthetic biology and systems biotechnology [1]. Due to the structurity laws [2] of the synthetic biosystems theory: 1).structure integration, coordinative organization of [...]

Visual Motion Analysis of Nanoplatforms Flow under an External Magnetic Field

Nakhmani A., Etgar L., Tannenbaum A., Tannenbaum R., Lifshitz E., Tannenbaum A., Tannenbaum R., Technion – Israel Institute of Technology, IL

We use the tools of nanotechnology and develop a visual tracking algorithm for motion analysis of nanoplatforms under the influence of an external magnetic field. We have studied quantitative relationships between nanoplatform sizes, fluid flow [...]

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, [...]

Effect of laser processing parameters and glass type on topology of micro-channels

Ben Azouz A., Brabazon D., Vázquez M., Macka M., Dublin City University, IE

Traditional techniques to manufacture micro-fluidic devices are well established but most are limited to surface micro-fabrication. Laser micro-machining provides an alternative technique for micro-fabrication of devices. This paper presents the fabrication of 3-D micro-channel structures [...]

Analysis of prediction capability for internal micro-channels fabrication in polycarbonate and PMMA

Karazi S.M., Brabazon D., Dublin City University, IE

This paper presents a 3^3 factorial Design of Experiment (DoE) and Artificial Neural Networks (ANN) for the prediction of two characteristics of the pulsed Nd:YVO4 laser machined internal micro-channels in Polycarbonate and PMMA glass. Power, [...]
