Myconi Technical Solutions for In Transit Visibility Cold Chain Logistics

McCleland B., Russell T.W., Myconi Technologies, US

Myconi Technologies has developed a proprietary wireless, ad hoc, peer-to-peer, self-healing mesh network protocol that operates on internationally license-free frequencies (IEEE 802.15.4 ISM Standard). Myconi has incorporated this wireless technology with multiple environmental and material [...]

Silicon Nanowire Vertical Arrays with Porous Top Electrodes for Trace Vapor Preconcentration and Partial Separation

Giordano B., Pehrsson P., Johnson K., U.S. Naval Research Laboratory, US

Commercial Off the Self (COTS) technologies for chemical vapor detection of trace analytes in complex, unknown background environments, often underperform with respect to sensitivity and selectivity. We have developed a chemical preconcentrator based on a [...]

Micro-Sized Power Controllers for Space

Frohling K., Iris Technology, US

The explosion in SmallSat and CubeSat deployments has led to a need for miniaturized cooling solutions for sensors that require cooling. Since there are limited opportunities for miniaturization in the thermal mechanical unit (TMU) portion [...]

Fast-reacting smart hydrogel-based sensor platform for biomedical applications

Koerner J., Reiche C.F., Leu H-Y, Magda J., Solzbacher F., University of Utah, US

Smart hydrogels are highly biocompatible polymeric materials which change their volume in the presence of an analyte they have been tailored for by molecular imprinting or aptamer-based approaches. These properties make hydrogels ideal candidates for [...]

Fully Transparent Field-Effect Biosensors

Du X., Herman G.S., Oregon State University, US

Amorphous indium gallium zinc oxide (IGZO) field effect transistors (FETs) are a promising technology for a wide range of electronic applications including implantable and wearable biosensors. We have recently developed novel, low-cost printing methods to [...]

Numerical Simulation of Flow and Heat Transfer of a Ferrofluid in a Partially Filled Porous Channel in a Gradient Magnetic Field

Mokhtare A., Jafari A., Furlani E.P., University at Buffalo, US

Unique interactions of ferrofluids with magnetic fields can be exploited to achieve enhanced heat transfer for myriad fluidic based applications. In this study, we use a numerical simulation to investigate the transient behaviour of flow [...]

Numerical modeling of the formation of dynamically configurable L2 lens in a microchannel

Gupta A., Kitting J., Karampelas I.H., Flow Science Inc., US

The aim of this presentation is to describe the numerical modeling of a dynamically reconfigurable liquid-core liquid-cladding (L2) lens in a microfluidic channel, followed by a quantitative validation against the experimental results [1]. The lens [...]

Design of Magnetic Blood Cleansing Microdevices through experimentally validated CFD modeling

Gómez-Pastora J., González-Fernández C., Karampelas I.H., Bringas E., Furlani E.P., Oriiz I., Flow Science Inc., US

Continuous flow bioseparators allow magnetic particles that are properly functionalized so that they get attached to dangerous pathogens, to be easily captured in a buffer solution. Specifically, the unique properties of magnetic particles enable their [...]

Microfluidic Test Target for Photoacoustic Imaging

Schneider P., Eadie N., Christie L., Zhan Y., Siskar T., Koh D., Xia J., Oh K.W., University at Buffalo's Sensors & MicroActuators Learning Lab (SMALL), US

Photoacoustic imaging involves the use of optics (typically a high power pulsed laser) and acoustics (ultrasonics frequency ranges >1MHz) to image a targeted object. Individually, these modalities, being optical and ultrasonic imaging, can be quantified [...]

Additive Manufacturing of Microfluidic Components via Wax Extrusion

Schneider P., Sukhotskiy V., Christie L., Siskar T., Karampelas I.H., Furlani E.P., Oh K.W., University at Buffalo's Sensors & MicroActuators Learning Lab (SMALL), US

Fused deposition modelling (FDM) has been extensively applied in the fields of rapid prototyping and 3D printing, but typically this technique has mostly been used for the fabrication of low melting point plastics. This paper [...]
