Development of MEMS auto-focusing mechanism for cell phone cameras

Micro-electromechanical systems (MEMS) refer to integrated mechanical & electrical systems in micron scale that are now growing in numbers due to a miniaturization trend. An advanced actuation method proposed for MEMS in University of Toronto and Ryerson University will be applied for an auto-focus mechanism in cell phone cameras. This research will build on work conducted by a six-member research team in both universities. The proposed MEMS autofocus not only has larger depth of focus, but also is faster than the current technologies, and is easier to implement.

Demonstration and Performance Evaluation of an Optimized Lab-scale Biogas-fuelled Heat and Electric Power Generation System Based on the Solid Oxide Fuel Cell

The build of an efficient, low cost, and environmentally friendly heat and power generation system for the use in single family detached dwellings, wastewater treatment plants, or landfills, is the objective of this project. This system is based on the solid oxide fuel cell and is designed to operate with biogas. We have successfully proved the advantages of this system over the traditional and other fuel cell-based systems developed in the United States and Europe, through computer simulation.

Developing a prototype electrowetting on dielectric device to perform immunoassays

The goal of this project is to develop a prototype microfluidic device to rapidly determine whether a target protein is present in a sample. Applications of this device include genomic and proteomic research, pharmaceutical testing, and quality control for various industries, including food preparation. The prototype will make use of electrowetting on dielectric (EWOD) actuation, which uses the application of electric fields to manipulate confined droplets. Unlike conventional microfluidic devices, EWOD devices do not require complex features for flow control or external pumping.

Hierarchical Heat Transfer Modelling in High-End Electronic Devices

One of the main challenges in the development of nano-scale devices is that the conventional physical relations and techniques, which have been used for modelling thermal problems at macro-scales, are no longer valid at these small scales.  In this project, we are developing a new hierarchial methodology to be applied to thermal management issues for nano-scale devices.  The impact of elecromigration in a joule heating form will also be explored.  Devices with nano-scale feature sizes are currently employed in high-end electronic systems.  In this method, we include the atomistic level effe

Flow velocity measurements in a gas turbine engine

The proposed project aims to reduce emissions and fuel consumption in the next generation of aircraft engines.  Better aerodynamics, higher efficiency and reduced weight are possible by improving the performance of the core engine components (ie.

Modelling of integrated biomass gasification and solid oxide fuel cell systems

Integrated solid oxide fuel cell and biomass gasification systems are one of the most promising energy technologies of the future. Usage of this system to utilize biomass yields better performance and environmental impact compared to the conventional biomass utilization technologies, e.g. steam turbine and internal combustion engine. However, to get the most benefit from this system, the configurations and operating parameters of this system should be optimized, which can be done through modeling.

Study of dielectric response in progressive tension-increase tests on stator windings on large rotating machines

Progressive tension-increase tests are one of the diagnostic methods currently used by Hydro-Québec for the stator isolation system on its hydro alternators. This test is part of MIDA, an expert diagnostics toolkit in use at Hydro-Québec. The effect of certain flaws affecting the quality of the signal during the test, especially with regard to the problem of copper-insulation delamination, has yet to be investigated.
