High Curvature Bending of Ultra-Thin Chips and Chip-on-Foil Assemblies

D. van den Ende[1]
[1]Holst Centre / TNO, Eindhoven, The Netherlands

Ultra-thin chips of less than 20µm become flexible, allowing integration of silicon IC technology with highly flexible electronics. This combination allows for highly intelligent products of unprecedented thinness, flexibility and cost. Examples include sensor systems integrated into ... En savoir plus

Electromagnetic Design of an RF-Coil Transceiver for NQR-Based Explosive Detection

P. Farantatos [1], J. Barras [1], I. Poplett [1], P. Kosmas [1],
[1] King's College London, UK

In the humanitarian demining setting, it is crucial to detect landmines with reliable sensing performance. As Nuclear Quadrupole Resonance (NQR) is an effective method for detecting explosive materials, our group is currently developing the world’s first low-cost system for anti-vehicle ...

Design and Simulation of 3D ZnO Nanowire Based Gas Sensors for Conductivity Studies

N. Gouthami, D. Parthiban, M. Alagappan, and G. Anju
PSG College of Technology
Coimbatore
Tamil Nadu, India

The objective of this paper is to design a 3D Gas Sensor for sensing Hydrogen gas and to increase the conductivity at nano level. In this novel design, nanorods act as the sensing layer. The sensitivity towards gas adsorption is found to be increased due to its high surface to volume ... En savoir plus

Remote Sensing of Electromagnetically Penetrable Objects: Landmine and IED Detection

R. Eze [1], G. Sivulka [2], ,
[1] City University of New York - LaGuardia Community College, Long Island City, NY, USA
[2] Regis High School, New York, NY, USA

The detection, characterization, and classification of underground environmental hazardous objects [mines, IEDs, and other unexploded military hardware] is a worldwide problem that needs urgent attention and solution. While electromagnetic sensor technologies have been applied to ... 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

Designing a Current Injection Tool for Logging While Drilling

B. Oetiker[1], B. Friedman[1], and H.E. Hall Jr.[1]

[1]Department of Physics, Sam Houston State University, Huntsville, Texas, USA

High-resolution imaging is useful in oil and gas exploration to identify producing fractures that can be in the millimeter thickness range. In principle, high-resolution imaging maybe achieved using “current injection” to measure the electrical conductivity of the formation. Two current ... En savoir plus

Finite Element Analysis of Microscale Luminescent Glucose Sensors in the Skin Dermis

S. Ali[1], and M. McShane[1]
[1]Department of Biomedical Engineering, Texas A&M University-College Station, Texas, USA

With the rising predominance of diabetes, successful management of blood glucose levels is increasingly important. Key efforts have focused on the development of optical microscale glucose sensing systems based on the encapsulation of glucose oxidase within microspheres coated with ... En savoir plus

Non-Isothermal Kinetics of Water Adsorption in Compact Adsorbent Layers on a Metal Support

G. Füldner, and L. Schnabel
Fraunhofer Institute of Solar Energy Systems, Freiburg, Germany

Water adsorption in highly porous materials can be used in heat transformation processes for the efficient use of energy in heat and cold production. One technology for such a thermal heat transformation is the use of water adsorption in highly porous adsorbents like zeolite. To ... En savoir plus

Simulation of Thermal Transport Based Flow Meter for Microfluidics Applications

E. Byas[1], A. Arevalo[1], I.G. Foulds[1]
[1]King Abdullah University of Science and Technology, Thuwal, Saudi Arabia

COMSOL Multiphysics® is used to simulate a thermal transport based flow sensor, which will be embedded in a micro-channel of a Poly-methyl methacrylate (PMMA) based microfluidic device. The channel height is 100μm and for simulation purposes the lengths has been set to 1.2mm. The heater ... En savoir plus

Detector and Calibration-source Models for the SAFARI Detector Test Facility

M. Audley[1], G. de Lange[1], C. Bracken[2]
[1]SRON Netherlands Institute for Space Research, Groningen, The Netherlands
[2]National University of Ireland, Maynooth, Ireland

SAFARI is a far-infrared imaging spectrometer for the Japanese satellite observatory SPICA. SAFARI covers the wavelength range 34—210 μm (1.4—8.8 THz) using Transition-Edge-Sensor (TES) bolometers. We have built a test facility to qualify and characterize the SAFARI focal plane units ... En savoir plus
