Continuous wearable bladder state detection technology through microwave sensing for urinary incontinence

Tuna Gedik, Emmanuel Menacho Tardieu, Karim Mustafa, and John Eric Hamilton (all from Bioengineering)

As a capstone project, our team is developing a bladder state detection device to help patients and elderly manage their urinary incontinence (UI). More specifically, we鈥檙e evaluating the feasibility of using a microwave antenna array to determine changes in bladder volumes, which would then be correlated with someone鈥檚 urge of needing to go to the bathroom. When antennas are placed on skin in front of the pelvic area, emitted microwaves pass through the body and are reflected back to the antennas, where changes in urine volume can be detected via the change in bulk dielectric properties. Patients with UI often lose a certain degree of control over their bladder, and may also lose the ability to sense when their bladder is full. Up to 35% and 60% of elderly men and women suffer from UI, respectively. When paired with other medical issues such as reduced mobility, managing this condition becomes a considerable challenge for both patients and healthcare workers. As the preliminary data we obtained showed promising results both in simulations and experimental testing, we see the potential of such a device being further developed for the sights of commercialization. The North American adult diaper market is currently evaluated at USD 5.6 Billion and is expected to grow at a CAGR of 6.2%. We foresee the potential for assistive medical devices to facilitate the management of UI alongside current diaper solutions to alleviate the burden on patients, caregivers and those who pay for the care of elderly.

Developing a rational device design for regulated drainage in glaucoma filtration surgery

David Bettan, Christopher Coluni, Adi Orlov, and Mark Tchinov (all from Bioengineering)

Surgical procedures increasing aqueous humor (AH) outflow, such as trabeculectomy and glaucoma drainage device (GDD) implantation, are performed to reduce intraocular pressure (IOP) and prevent further optic nerve damage in patients with refractory glaucoma. Among many factors, long-term surgical success has been attributed to the filtering capability of the formed bleb, a blister-like fluid collection. While studies have investigated key bleb parameters and morphologies associated with ideal functionality, its transient formation process remains poorly understood. The goal of this project is to develop a novel device for regulated AH flow in glaucoma management, which includes bleb formation and fluid mechanics at the core of its design. At the early stages of the postoperative period while the bleb remains immature, the patient is prone to over-drainage of AH, which can lead to a dangerous drop in IOP. Clinicians have attempted to regulate the outflow of AH in both trabeculectomy and GDD with inconsistent success. As a result, an internally conducted survey of 75 licensed ophthalmologists shows that approximately 98% of clinicians seek a device capable of regulating AH through the GDD in the initial weeks after surgery, without the need for a mechanical valve or ligation step. In addition, studies on these procedures showcase a success rate of 56-68%. As a result, this interdisciplinary project has the potential to generate new biomedical devices for improved and effective glaucoma management.

Ghali Qaidi, Abdullah Taltello, Larissa Azzopardi, and Alois Luong (all from Mechanical Engineering)

Our capstone project focuses on designing, building, and testing a highly repairable and easily manufacturable VTOL quadplane UAV that seamlessly transitions between vertical (rotor-based) and wing-borne (fixed-wing) flight. This UAV serves as a dedicated test platform for refining flight transition strategies, optimizing control algorithms, and training the next generation of drone pilots. We aim to make advanced quadplane technology accessible to teams and students who may lack the resources to develop their own. By offering an affordable, modular, and open-source solution, our UAV removes barriers to entry, allowing users to test autonomy, compete in flight challenges, and explore new applications without requiring extensive mechanical expertise or specialized equipment. With an adaptable design, the use of off the shelf electronics, and extensive expandability, this quadplane is a powerful tool for research, inspections, and field operations. It is built to be modified and customized, empowering users to tailor it to their specific needs鈥攚hether for academic research, industrial applications, or competition.

Multi-Camera Surgical Tool Localization Setup for Image-Guided Neurosurgery

George Sideris, Justin Cree, Andrew Stirling, and Mamadou Ly (all from Mechanical Engineering)

Our project included the design (both mechanical and software) and fabrication of a multi-camera surgical tool localization setup for image-guided neurosurgery. Image-guided neurosurgery entails the modelling of critical structures in the brain, such as tumors and blood vessels, and the tracking of surgical tools in relation to these models. This tracking enables the surgeons to visualize the position of their tools in relation to the critical structures in real-time, allowing them to plan tumor removal approaches before performing a craniotomy (analogous to 'x-ray' vision). Our solution has the potential to greatly improve the user experience of neurosurgeons by limiting any obstructions to their view or mobility in comparison to state-of-the-art tool localization systems. Further, its greatly reduced cost will enable image-guided surgery technologies to become accessible to many hospitals within Canada and around the world which lack the funding for currently available systems.

Maya DeCruz, Anita Kriz, Zoe Goldberger, Grace Reszetnik, and Alexandra Magliocco (all from Bioengineering)
At elleFA, we are working to develop a solution that can address the shortcomings in the diagnosis and treatment of endometriosis. In all, our centralized platform is composed of three goals (1) screen for endometriosis biomarkers correlated with the disease with our at home test kit (2) track biomarkers, symptoms, and intervention responses over time with our app and (3) connect doctors and patients with quantitative results and qualitative symptoms. To screen, we are developing an at-home lateral flow assay (LFA) kit, the same technology used to make pregnancy tests. With this kit, women can quickly see their urine levels of prognostic biomarkers that are correlated with endometriosis in the comfort of their homes. Throughout their treatment journey, they can continue to use this kit to evaluate the progression of their disease. To further ease patients in the tracking of their disease management, we are simultaneously developing an app in which patients can record symptoms, screening results, and responses to treatments in a novel format endorsed by the stakeholders we have partnered with. Our third and final goal will be met through the app by organizing various patient information in a format that is easy for both the physicians and the patient to understand. To facilitate communication between the two parties, we will provide resources through the app that will make monitoring efficient, direct and simple.

Reconstructing the Esophageal Tumour Microenvironment: Development of an ECM Hydrogel to Host Tumour Spheroids

Madison Santos, Ariel Corsano, and Isabelle Dummer (all from Bioengineering)

Mimicking the mechanical properties of the tumour microenvironment (TME) is essential in cancer models, as mechanical changes impact the ability of drugs to reach the tumour core. However, in vitro cell monolayer models lack the three-dimensional aspect of the TME, and in vivo small animal tumour xenografts introduce non-human factors into tumour growth. We propose a 3D in vitro tumour model that mirrors the biomechanical and pathophysiological characteristics of esophageal cancer. We have formulated a material incorporating structural proteins and retaining physical and biomolecular cues to promote native cell proliferation. The compositional and structural material characterization was used to appropriately tune the material mechanical properties to imitate esophageal tissue mechanics. To this end, alginate-gelatin hydrogels of varying concentrations have been synthesized and characterized by rheometry. Decellularized extracellular matrix (dECM) was selected as a bioactive additive for the tumour models and was obtained by enzymatic decellularization of porcine gastric tissue. The biochemical composition of the dECM was evaluated by spectrophotometric assays to confirm successful decellularization and structural protein content. Cancer cell viability and expansion in spheroid culture were evaluated within the new material. Overall, this biologically derived spheroid tumour model is expected to improve the accuracy of existing tumour models, which will increase understanding of esophageal cancer proliferation, mechanics, and immune response, which will be used to inform treatment plans and patient outcomes.
