Evaluation of Binary Mixture Models for 3D Printed Biosensors

J. Persad [1], S. Rocke [1], D. Ringis [1], A. Abdool [1],
[1] Department of Electrical and Computer Engineering, University of the West Indies, St. Augustine, Trinidad and Tobago

3D printing as applied to the area of electronics manufacture covers a broad range of traditional printing technologies [1]. The attraction in 3D printing lies in its potential to disrupt the traditional photolithographic/subtractive manufacturing line with simpler additive processes. ... Read More

Analysis of Magnetically-coupled Human Body Communications

S. A. Rocke [1], Daniel Ringis [1], Jeevan Persad [1],
[1] Department of Electrical and Computer Engineering, The University of the West Indies, St. Augustine Campus, Trinidad and Tobago

Human body communications (HBC) uses the human body as a transmission medium to connect sensors and actuators in, on or in close proximity to the human body. The HBC approach offers tremendous potential for the design and implementation of emerging personalized healthcare systems, as ... Read More

Electron Drift in Xe Gas

T. J. Berger [1],
[1] Department of Physics, Applied Physics, and Astronomy, Rensselaer Polytechnic Institute, Troy, NY, USA

The XENON Dark Matter Experiment utilizes ultra-pure xenon (Xe) as a target for particle interaction in the effort to detect dark matter particles. To measure the purity of Xe, a gas purity monitor (GPM) is being developed which drifts electrons through Xe gas to detect impurities that ... Read More

Comparison of Magnetic Barkhausen Noise Tetrapole and Dipole Probe Designs

P. R. Underhill [1], T. W. Krause [1],
[1] Department of Physics, Royal Military College of Canada, Kingston, ON, Canada

COMSOL Multiphysics® software is used to understand the difference in behaviour of two Magnetic Barkhausen Noise (MBN) probes. The dipole probe has to be physically rotated to sample the angular distribution of the MBN. The tetrapole probe uses vector superposition to rotate the magnetic ... Read More

Skin Variations Impact on Non-Invasive Measurement of Blood Glucose with Interdigital Electrodes

J. Persad [1], S. Rocke [1],
[1] Department of Electrical and Computer Engineering, University of the West Indies, St. Augustine, Trinidad and Tobago

This work aims to investigate the behaviour of a simple interdigital sensor structure for glucose monitoring in response to distortions in the skin-topology and differences in skin undulation during use. The study then extends to consider a flexible sensor structure which is better able ... Read More

Simulation of the Impedance Response of Thin Films as a Function of Film Conductivity and Thickness

Y. Jin [1], S. Kumar [1], R. A. Gerhardt [1],
[1] School of Materials Science and Engineering, Georgia Institute of Technology, Atlanta, GA, USA

Introduction The electrical properties of materials are important in many different applications. In microelectronics for example, films must perform as insulators, semiconductor or as conducting layers. In recent years, scanning probe methods are being extended to the nanometre scale ...

Impact of Electro-Convection (EC) on Heat Transfer in Liquid-Filled Containers

A. Pokryvailo [1],
[1] Spellman High Voltage Electronics Corporation, Hauppauge, NY, USA

Electric field can bring liquid in motion and thus influence heat transfer. Electro-convection (EC) can be caused by electric forces acting on a liquid, even in absence of space charge. Here, we studied heat transfer in a metal vessel filled by oil, with a submersed high voltage ... Read More

Particle Concentration Effect On Dielectrophoretic Trapping

M. A. Saucedo-Espinosa [1], B. H. Lapizco-Encinas [2],
[1] Department of Microsystems Engineering, Rochester Institute of Technology, Rochester, NY, USA
[2] Department of Biomedical Engineering, Rochester Institute of Technology, Rochester, NY, USA

Dielectrophoresis (DEP) is an electric field driven technique that has important applications in the enrichment, concentration and isolation of biological and non-biological particles. The assessment of particle trapping capacity using DEP, however, has been qualitative in nature; since ... Read More

Optimization of Insulator-Based Dielectrophoretic Devices

M. A. Saucedo-Espinosa [1], M. Rauch [1], B. H. Lapizco-Encinas [2],
[1] Department of Microsystems Engineering, Rochester Institute of Technology, Rochester, NY, USA
[2] Department of Biomedical Engineering, Rochester Institute of Technology, Rochester, NY, USA

Insulator-based dielectrophoresis (iDEP) employs arrays of electrically insulator posts in a microfluidic device to create dielectrophoretic forces that affect particle movement (Figure 1). The trapping performance of iDEP devices involves a careful balance between electrokinetics (EK) ... Read More

Design of a Dielectrophoretic Based Micropipette for Gene Expression Applications Using COMSOL Multiphysics® Software

D. Wijesinghe [1], K. Nawarathna [1],
[1] Department of Electrical and Computer Engineering, North Dakota State University, Fargo, ND, USA

We have used COMSOL Multiphysics® software to design a micropipette for single -cell gene expression profiling. The micropipette design allows us to insert it into a single-cell to extract genes through dielectrophoresis. As dielectriphoretic force depends on the applied electric field ... Read More
