P4 鈥� Multi-Camera Surgical Setup for Image-Guided Neurosurgery

Project Category: MEDTEC - Faculty

Dr. Louis Collins听/ Dr. Houssem Gueziri听

One of the most important components for image-guided neurosurgery is the ability to accurately track surgical instruments during navigation. This can be performed using a high-end infrared (IR) camera and reflective spheres or a low-cost standard RGB camera and printed markers. Despite their ability to collect the spatial position and orientation of a surgical instrument, these optical systems face challenges such as occlusion and limited visibility, which restrict the surgeon's operative movements. To overcome these limitations, one proposed solution involves the placement of multiple tracking cameras around the operative field. These cameras would offer various perspectives and coverage during surgery. Yet, combining multiple tracking sources is not straightforward. In addition, each source would yield different tracking accuracy depending on the markers distance, configuration, visibility, orientation, lighting conditions and other external factors.

P9 鈥� 缅北强奸 Baja Racing MB24-CVT Capstone

Project Category: 缅北强奸 Design Team

缅北强奸 Baja Racing

This project aims to design, manufacture, and implement custom CVT components for MB24, 缅北强奸 Baja Racing鈥檚 forthcoming vehicle. The preceding CVT in MB23 aimed to refine our mechanically successful design from years prior in order to optimize it for traction limited acceleration. Practical testing was conducted in order to determine the engine RPM and Torque curves, drag coefficient, rolling resistance and other parameters to model the theoretical traction limited acceleration of MB23. This was used to determine ideal transmission ratios, from which clutch dimensions, spring rates and flyweight masses within the CVT were optimized for. However, as the system is solid state this optimization achieved a balance between top speed and acceleration performance, rather than maximizing any one in particular.

P10 鈥� Large scale design and implementation of algae collection and cultivation device (Algo)

Project Category: Mechanical Engineering - Industry

Biocene Solutions (startup)

Algal blooms present a significant environmental challenge, characterized by the detrimental overgrowth of algae in water bodies due to elevated temperatures, agricultural runoff, and industrial waste. These blooms result in diminished oxygen levels in water, blockage of sunlight crucial for aquatic life, and the release of harmful toxins. Addressing this issue, Biocene Solutions鈥� Algo is an innovative solution that employs specialized devices within water bodies to regulate and manage algae levels. The collected algae can then be repurposed for biomass production or to create biofuel, biochar, compost, fertilizer, pigmentation, animal feed, and other value-added products. Unlike existing solutions, which often involve using harmful chemical solvents or expensive ultrasound treatments that eliminate algae but also disrupt ecosystems, Algo takes a different approach. By harvesting the algae and transforming it into biomass, Algo not only aids in revitalizing water bodies impacted by algal blooms but also generates a valuable resource in the form of organic fertilizer and clean energy.

P13 鈥� Design and transformation of lathe machining process and tooling

Project Category: Mechanical Engineering - Industry

Pratt and Whitney Canada

Pratt and Whitney Canada, is a leading aviation company, seeks to address a critical manufacturing challenge related to the turning process of disks which are used in the development of aircraft engines. The disks possess specific geometry, such as thin walls, circular shapes, and complex edge definitions,

which together with the material properties, pose difficulties in securely clamping the material during the turning process. The current clamping issue poses safety concerns, as it may lead to accidental part disengagement due to the high forces involved in the turning process. Conversely, excessive clamping force can cause deformation of the delicate part material, compromising the overall quality and performance of the engine component. This issue results in significant downtime for the machine, requiring frequent pauses by the operator to adjust the clamping and positioning of the part.

P14 鈥� A wearable monitor for detecting bladder fullness

Project Category: MEDTEC 鈥� Faculty

Prof. Emily Porter

Urinary incontinence (UI) affects more than 200 million individuals worldwide, and is particularly prevalent in women, the elderly, those with spinal cord injuries, and children and young adults with intellectual or developmental disabilities. UI can have a significant negative impact on an individual鈥檚 quality of life, independence, and dignity. A wearable device that provides an alert as the bladder is approaching full could be very valuable in allowing users to void on time. A support tool for those with UI should be safe for 24/7 use, non-invasive, low-cost, and discreet. This project will focus on the design of a wearable bladder monitoring for detecting when the bladder is full of urine

P18 鈥� Shock-absorbing High Heel Shoe (mechanical engineering, biomimetic design)

Project Category: MEDTEC 鈥� Faculty

Prof. Natalie Reznikov

High heel shoes are popular for their aesthetic effect despite the overt discomfort for the wearer. The elevation of the heel constraints the natural shock-absorbing quality of the human foot, and disadvantageously shifts the body weight to the forefoot. While some wearers develop impressive poise on high heels, most wearers experience fatigue, rigidity of the gait, foot arch deformities, and even foot injuries and lower back pain.

P23 鈥� Development of a double ventricular dynamic phantom to assess microvascular lung hydraulic resistance

Project Category: MEDTEC - Faculty

Prof. Rosaire Mongrain

Pulmonary circulation plays a crucial role in oxygenating the blood and ensuring that the body's vital organs
receive the necessary oxygen to function properly. Unfortunately, disorders related to the pulmonary
circulation system can lead to serious health problems and even death. In particular, for premature babies,
pulmonary vascular resistance (PVR) is one the best indicator of survival. The means to measure PVR are
limited and especially in a non-invasive context. The ultimate goal of the project is to refine a new
mathematical model for the evaluation of PVR using imaging data and peripheral pressure assessment as
diagnostic tool.听

P26 鈥� Wrapping Fluids in Air for Zero Contact Flow

Project Category: Mechanical Engineering - Faculty

Prof. Reza Farivar and Prof. Rosaire Mongrain

Algae have one of the highest rate of photosynthesis, and industrial algae production contributes to not only intense carbon capture, but production of organic fertilizer and nutritional supplements. Modern bioreactors for algae growth use a series of translucent tubes to expose the algae growth media to the sun and induce photosynthesis, but a persistent challenge with these designs is the fouling of the translucent tubes by organic matter. This problem persists even with various coatings, and more intense coatings have a risk of decreasing the available sunlight, thereby reducing growth efficiency.

P27 鈥� Design of PCR chambers for improved cooling speed

Project Category: Mechanical Engineering - Industry

Prof. Andrew Kirk

The polymerase chain reaction (PCR) is widely used to amplify and identify DNA samples and is now well-known as providing the most sensitive test for COVID19. Most commercial PCR systems require over an hour to produce a result, but we have demonstrated a new approach that uses laser heating of gold nanoparticles to drive the reaction [1, 2]. This has allowed us to produce test results in under ten minutes and opens the technique up to point-of-care applications. In the PCR system, samples (10-20 microlitres of liquid contained in a 100 microlitre thin-walled plastic tube) must be cyclically heated and cooled between 55 degrees C to 92 degrees C. Typically 3- to 40 cycles are run, and DNA product is measured in real-time using fluorescence methods. In the current system, the rate of cooling has become one of the main limitations to speed. While in the past we have experimented with cooling via chilled air, we have not previously considered optimizing the design of the PCR tube for cooling.

P31 鈥� Development of an environment cell for in situ battery testing

Project Category: Mechanical Engineering 鈥� Faculty

Prof. Changhong Cao

While Li-ion batteries (LIBs) has been the most important energy storage system for electronic vehicles (EVs) and devices, an ever-increasing demand for higher energy and power densities, higher charging rates, higher Coulombic efficiencies, longer cycle life, and better safety are driving the need for a greater understanding of battery materials on the microscopic-to-atomistic scale. Numerous important processes occur at/through the solid/liquid interfaces of battery electrodes and hence it is pivotal to understand processes at these interfaces when exploring performance improvement methods for LIBs or related alkali ion batteries. Atomic force microscopy (AFM) and other advanced scanning probe microscopy (SPM) techniques are recently becoming crucial platforms for the study of battery materials, enabling the versatile characterization of the morphological, mechanical, local-electrochemical, and other physical properties of battery materials in situ as they undergo charge and discharge processes.
