Neural Network-Based MEMS Failure Probability Prediction

Ilumoka A.A., Tan H., UNIVERSITY OF HARTFORD, US

MicroElectronic and Mechanical Systems (MEMS) are a blend of microelectronic and mechanical devices closely coupled and simultaneously manufactured to monitor, analyze, and control everyday processes such as automobile function, biological systems operation and aeronautical flight. [...]

Angular Orientation-Specific Directed Self-assembly Enabling the Integration of Small Dies

Knuesel R.J., Bose S., Zheng W., Jacobs H.O., University of Minnesota, US

We report on recent progress in the directed self-assembly of discrete high performance semiconductor device components. Different from prior research, the goal is to enable the integration of ultra small dies (10-100 micrometer in size) [...]

Development of Materials and Sensors for the U.S. Army’s Active Coatings Technology Program

Zunino III J.L., U.S. Army ARDEC, US

The ability to custom build and integrate novel technologies into functionalized systems is the driving force towards the creation and advancement of active coatings systems. Active coating systems require the development and advancement of numerous [...]

FEM Simulation for demolding process in thermal imprint lithography

Song Z., Lee J., Park S., Louisiana State University, US

Thermal imprint lithography is a highly potential technique utilizing molding to produce micro- and nano-structures with high throughput and at low cost. Extensive researches have been performed in understanding polymer flow behavior and cavity filling [...]

Modeling and Dynamics of Coupled Dome-shaped Micromechanical Oscillators

Sahai T., Zehnder A.T., Cornell University, US

In this work we analyze a feasible approach for constructing coupled micromechanical oscillators that synchronize. For this purpose we use dome shaped micro-oscillators that have previously been used to build radios. These oscillators are fabricated [...]

Frequency Domain Modeling of SAW Devices

Wilson W.C., Atkinson G.M., NASA Langley Research Center, US

The lack of integrated design tools for MEMS devices in general, and for Surface Acoustic Wave (SAW) devices specifically, has led to the development of tools that will enable integrated design, modeling, simulation, analysis and [...]

Microfluidics and Microacoustics for Miniature Flow Cytometry

Ravula S.K., Branch D.W., Sigman J., Clem P., Kaduchak G., Brener I., Sandia National Laboratories, US

Flow cytometry is an indispensable tool in clinical diagnostics, for example in cancer, AIDS, infectious disease outbreaks, microbiology, and others. The cost and size of existing cytometers precludes their entry into field clinics, water monitoring, [...]

A Model for Blood Cell Transport and Separation in a Magnetophoretic Microsystem

Furlani E.P., University at Buffalo, US

We present a model for predicting the transport and separation of red and white blood cells in plasma in a magnetophoretic microsystem. The microsystem is passive and consists of an array of integrated soft-magnetic elements [...]

A Silicon Ultrasonic Imager Probe for Minimally Invasive Diagnosis

Chen J.K., Chen S-Y, Cheng X., Lin P., Cheng X., Liu J-H, Chen J.K., Chen S-Y, Cheng X., Li P-C, Lin P., Liu J-H, Xerox Corp, US

This paper reports the development of a miniaturized ultrasonic transducer array for minimally invasive medical imaging. This probe shape ultrasonic transducer array is smaller than a human hair. Due to its miniature size, this array [...]
