New Analysis Method for Coupled-Field Micro Devices

Motiee M., Khajepour A., Mansour R.R., University of Waterloo, CA

MEMS actuators are typically used for either one time deployment of structures for automatic assembly or constant periodic actuation as in case of micro optic scanners. Electro-thermal actuators rely on the joule heating resulting small [...]

MEMS Sensors for Harsh Environment Applications

Nieva P.M., University of Waterloo, CA

Micro Electro Mechanical Systems (MEMS) for harsh environment applications are becoming increasingly important. They are recognized as essential for reducing weight and volume in strategic market sectors such as automotive, aerospace, turbomachinery, oil well/logging equipment, [...]

Prevention and Risk Reduction in Heart Health

Kaminska B., Tavakolian K., Ngui B., Chuo Y., Carmichael B., Simon Fraser University, CA

Identifying early onset of cardiac disease is not easy and it is very expensive. For this reason the first symptom of cardiac problems is often catastrophic. It is the goal to produce a low cost [...]

Evaluation of silver nanostructures fabricated using glancing angle depostion as localized surface plasmon resonance biosensors

Gish D.A., Nsiah F., McDermott M.T., Brett M.J., University of Alberta, CA

The localized surface plasmon resonance (LSPR) biosensing capability of 175 nm thick silver nanoparticle films produced by glancing angle deposition (GLAD) was evaluated. The extinction spectra of the films exhibited a peak around a wavelength [...]

Microfluidic electromanipulation with capacitive detection for cell diagnostic applications

Ferrier G.A., Hladio A.N., Thomson D.J., Bridges G.E., Hedayatipoor M., Olson S., Freeman M., University of Manitoba, CA

We are proposing an all-electrical approach to mechanical cell diagnostics that uses a combination of electromanipulation for stimulus and capacitance for sensing. We have successfully used the capacitive sensor to detect the electrical trapping (using [...]

Nitrocellulose-Stabilized Silver Nanoparticles as Low Conversion Temperature Precursors for Inkjet-Printed Electronic Circuits

Nguyen B.T., Nguyen M.T., Gautrot J.E., Nguyen B.T., Nguyen M.T., Zhu X.X., Université de Montréal, CA

Liquid-based inkjet printing is considered as a constructive (rather than destructuve) low-cost technique for printed circuit boards fabrication. A convenient way of depositing silver films and lines using inkjet technology is to generate silver nanoparticles [...]

The Innitial Reverse-Bias Injecting P+-N Junction Mode in P+-N-P+- Structures with Punch-Through

Mats I., Diatex, Selected Texno-Fix, CA

The Volt-Ampere Characteristics (VAC)s of P+NP+-structures in the schemes with floating base and short-cut p+-n junction (emitter) in punch-through modes were calculated before. It is important to research a behavior for similar structures but with [...]

Light Induced Self-Inscription (LISI) in Organo-silica Network Glasses and Nanocomposite Polymers

Andrews M.P., Belanger N., Manseau M.-P., Duxin N., Maron E., Lofgreen J., van Veggel F.C.J.M., McGill University, CA

This talk focuses on two classes of nanocomposite media that exhibit Light Induced Self Inscription. We describe LISI in sol-gel derived photosensitive glasses containing nanodispersions of zirconia, titania and noble metal nanoparticles. Waveguiding at 488 [...]

Porous filter with spatially graded response

Krause K.M., Hawkeye M., Brett M., University of Alberta, CA

Glancing Angle Deposition (GLAD) has become a common technique for producing thin porous films with various structural features. In the current work, we have further modified GLAD in order to create porous structures that have [...]

Optical and structural characterization of nanostructured Alq3 with negative in-plane birefringence

Szeto B., Gospodyn J., Hrudey P.C.P., Sit J.C., Brett M.J., University of Alberta, CA

In this study, we investigate the optical and structural properties of tilted columnar thin films composed of Alq3 in order to better understand the source of the in-plane birefringence exhibited by such films which is [...]
