Thermal-Optical Modeling of a Signal Enhancement Approach for Paper-Based Diagnostics

D. Gasperino [1]
[1] Intellectual Ventures Laboratory, Bellevue, WA, USA

INTRODUCTION: Point of care diagnostics aimed at low-resource settings need to be relatively simple, robust and low-cost. The most commonly-used diagnostic platform in these settings is the lateral flow assay (LFA). LFAs are paper-based immunoassays designed to perform on-strip binding ... En savoir plus

Electrochemical Characterization of the Microband Graphite Electrodes

A. V. Volkov [1], A. N. Sekretaryova [2], I. V. Zozoulenko [1], A. P. F. Turner [2], M. Yu. Vagin [2], M. Eriksson [2]
[1] Laboratory of Organic Electronics, Department of Science and Technology, Linköping University, Norrköping, Sweden
[2] Department of Physics, Chemistry and Biology, Linköping University, Linköping, Sweden

The microband design of microelectrodes is a cost-effective and easily-fabricated compromise combining convergent mass transport, due to microscale width as a critical dimension, and high output currents due to the macroscopic length. Among the various techniques available for microband ... En savoir plus

Air Damping Simulation of MEMS Torsional Paddle

N. Mahmoodi[1], C. J. Anthony[1]
[1]University of Birmingham, Birmingham, UK

Viscous damping has a significant effect on dynamic performance of the resonators operating within fluid. This work is aimed to find the viscous damping for MEMS torsional paddle operating in air. Interaction of moving structure with the fluid requires a complicated and challenging ... En savoir plus

Design and Simulation of Capacitive Pressure Sensor for Condition Monitoring

S. Sushma[1], R. Surekha[1], K. J. Rudhresha[1], S. Sahu [1], S. Singh4 [1], S. L. Pinjare6 [1],
[1] Dept. of ECE, Nitte Meenakshi Institute of Technology, Bangalore, Karnataka, India.

This poster focuses on the development of a capacitive pressure sensor for condition monitoring applications. One method to measure vibrations is to mount an pressure sensor on the vibrating machinery or object and measure the pressure exerted due to vibrations. Measured pressure level ... En savoir plus

Design and Simulation of a Microelectromechanical Double-Ended Tuning Fork Strain Gauge

H. H. Zhang [1], A. Bardakas [1], W. D. Leon-Salas [1],
[1] School of Engineering Technology, Purdue University, West Lafayette, IN, USA

Strain gauges have been extensively used for detecting strain in various applications. Double-ended tuning fork (DETF) strain gages present better performance characteristics than standard foil gauges, including higher sensitivity, smaller size and higher resolution. This study focuses ... En savoir plus

Comparative Study on 3D Modeling of Breast Cancer Using NIR-FDOT

S. Peter[1]
[1]Christ University, Bengaluru, Karnataka, India

Fluorescence Diffuse Optical Tomography (FDOT) uses Near Infra-Red (NIR) light to monitor physiological changes in internal organs. NIR light being less energetic in nature can be used for continuous monitoring of tumor infected biological tissue, neonatal brain and many such ... En savoir plus

COMSOL Multiphysics® Software for Simulation of Surface Response to Excitation Method for Manufacturing Process Performance Monitoring

H. Fekrmandi[1], N. Miniello[1], R. Kiflemariam[1], I. Nur Tansel[1]
[1]Mechanical & Materials Engineering Department, Florida International University, Miami, FL, USA

In this study, COMSOL Multiphysics® software was used to simulate the surface response to excitation method (SuRE). An aluminum beam with a piezoelectric element bonded is modeled using the COMSOL Acoustics Module. A frequency domain sweep study was performed to simulate the sweep sign ... En savoir plus

Effect of a High Frequency Field on the Electric Double Layer Surrounding a Biomolecule in a Fluid

M. Riou[1], C. Maedler[1], S. Erramilli[1], P. Mohanty[1]
[1]Boston University, Boston, MA, USA

Biosensors based on silicon nanowires are of great interest for ultrasensitive biomolecular recognition of disease specific markers for early stage diagnosis [1]. However, there are limitations on the performance of these nanosensors in solutions at high ionic strength. This is because ... En savoir plus

T. Bender [1], M. Sass [1], W. Mittelmeier [1], R. Bader [1], D. Kluess [1]
[1] Department of Orthopaedics Research Laboratory for Biomechanics & Implant Technology, University Medicine Rostock, Rostock, Germany

A finite element model of a total hip replacement (THR) has been developed from the approach of modal analysis. The model is capable of determining the first 15 Eigenmodes of a THR with an artificial bone model. The model was equipped with several different defects to simulate a ... En savoir plus

Model of Biosensor based on Organic Electrochemical Transistors

A. Shirinskaya [1], Y. Bonnassieux [1], G. Horowitz [1],
[1] LPICM, CNRS, Ecole Polytechnique, Université Paris Saclay, Palaiseau, France

One of the most promising categories of semiconductor-based sensors is organic electrochemical transistor (OECT), which consists of three electrodes (Source, Drain and Gate) and two active layers: electrolyte and conductive polymer. Despite the fact that OECT attracts a lot of attention ... En savoir plus
