Polymeric Nanowire Architectures and Nanodevices

Liu H., Kameoka J., Verbridge S., Craighead H.G., Cornell University, US

We devised a method, named as scanned electrospinning technique, to form a variety of one-dimensional polymeric nanostructures. It is a straightforward technique that enables the rapid fabrication of oriented polymeric nanowires as well as their [...]

Nanomechanical Sensor Platform Based On Piezo-Resistive Cantilevers

Thaysen J., Havsteen Jacobsen M., Kildemark Nielsen L., Cantion A/S, DK

Cantion has developed a piezo-resistive cantilever sensor for the detection of molecular interactions. The Cantion technology has been used for the detection of plastic explosives, DNA and proteins. The small sensor and readout footprint makes [...]

Smart, Intelligent and Cogent Microsensors – Intelligence for Sensors and Sensors for Intelligence

Gaura E., Newman R.M., Coventry University, UK

The paper develops a terminology to describe sensors which have been enhanced in some way by the integration of some additional processing circuitry. Several terms, current in the literature, including 'smart sensors' and 'intelligent sensors' [...]

System Issues in Arrays of Autonomous Intelligent Sensors

Newman R.M., Gaura E.I., Conventry University, UK

This paper considers some of the systems level issues of concerned when building of large scale sensing systems composed of a large number of autonomous intelligent sensors. The work is motivated by the potential offered [...]

Design of Performance-Enhanced Fabry-Perot Micro-Cavity Structure With a Novel Single Deeply Corrugated Diaphragm

Wang W.J., Lin R.J., Guo D.G., Nanyang Technological University, SG

The silicon micromachining technique has been successfully applied to the fabrication of miniature Fabry-Perot sensors. This kind of sensor detects changes in optical path length induced by either a change in the refractive index or [...]

Effects of Structural Deformation and Tube Chirality on Electronic Conductance of Carbon Nanotubes

Svizhenko A., Maiti A., Anantram M.P., NASA Ames Research Center, US

A combination of large scale classical force-field (UFF), density functional theory (DFT) and tight-binding Green’s function transport calculations is used to study the electronic properties of carbon nanotubes under the twist, bending and AFM-tip deformation. [...]

Biochemical Binding in Microspheres-Based-Imunoassays

Prabhakarpandian B., Shah K.B., Sundaram S., Makhijani V.B., CFD Research Corporation, US

Microspheres (referred commonly as beads) are being extensively used in biochemical assays as supports for proteins, DNA, etc. We have successfully developed |omputational models for simulating sample detection using flowing beads. The model fully integrates [...]

Analysis of Anodic Bonding and Packaging Effects in Micro Sensors

Shing T-K, Industrial Technology Research Institute, TW

Anodic bonding is quite popular in making micro-sensors since it can bond sodium-rich glass to silicon or virtually any metals with good adhesion strength in lower temperature. It is well known that this process will [...]

Simulation for Low Temperature Coefficient Design of Piezoresistive and Hall Sensors

Matsuda K., Kanda Y., Naruto University of Education, JP

Simulation for the temperature coefficient of piezoresistive and Hall sensors is presented. Carrier and ionized impurity concentrations in the n-type silicon gage are calculated from the charge balance equation by applying Newton iteration scheme. The [...]
