A helmet and its components such as chin strap are designed, tested, and certified for compression force only while neglecting sharp twisting of the brain. The goal of this project is to develop and integrate a Force Sensitive Mechanism (FSM) to a chin strap of a football and bicycle helmet. FSM offers a controlled tightness […]

Piezoresistive strain sensors respond to a mechanically induced deformation with a change in their electrical resistance. Large strain flexible strain sensors have been adopted for numerous applications including rehabilitation, health and sport performance monitoring as well as physiology and kinesiology applications. Although development of these flexible strain sensors has reached a level of maturity, design […]

The ability for an autonomous robot to create its own map based on onboard sensors and simultaneously, localize itself within this map is know as Simultaneous Localization and Mapping (SLAM). Although the theory behind SLAM has been well developed much work still needs to be done in realizing SLAM solutions that meet situation-specific real-world requirements. […]

The project aims at accomplishing the real-time delineation of both Seismocardiogram and Gyrocardiogram signals (which are associated with different stages of the cardiovascular cycle) and effectively extracting cardiac performance metrics (fiducial points) for use in a non-invasive portable diagnostic tool as the deviations of the either timing or amplitude can be indicative of abnormality in […]

Tracking the component configuration and modifications to aircraft within the commercial airline business presents a challenge for manufacturers such as Bombardier with currently available methods. This research problem is significant to the aerospace industry to construct efficient maintenance schedules for different aircraft and to properly evaluate system reliability for safety purposes. The objective of this […]

The remote First Nations communities of Canada suffer from a dire lack of access to emergency response systems and services during times of crises. They lack access to life-saving services such as paramedics, 911 services, and search and rescue services due to their geographic isolation. This often puts them in grave danger and results in […]

Ideal flow, high-volume Powder Metallurgy (PM) manufacturing can achieve uniform, consistent filling of die cavities, leading to high productivity, low rejection rates, improved part integrity and consistent part dimensions. The type and amount of lubricant, size and shape of lubricant particles, mixing parameters and certain environmental conditions all significantly influence the flow characteristics and apparent […]

Electrocardiography or ECG is a technology that can be used to monitor the electrical activity of the heart over a long period of time. Such signals can be utilized for interpreting both the structure and function of the heart. Traditional ECG designs consist of several electrodes that need to be placed directly in contact with […]

This study focus on the understanding of radiation-induced embrittlement in CANDU reactor spacer material, Inconel X-750. The helium pre-implantation following by proton irradiation will be employed as a surrogate for neutron irradiation to simulate the radiation damage on the microstructure of Inconel X-750. Micro-tensile test on irradiation X-750 material will be carried out to evaluate […]

Contamination in soil and groundwater tends to be overlooked since their adverse impact does not appear exteriorly and instantaneously. However, the contaminants could potentially cause adverse impact on vegetation and human health by migrating off the contaminated site through groundwater flow, and also influence climate change through cycling of elements. Recently, demand for remediation of […]

The proposed research aims at increasing the efficacy of tidal turbines by incorporating light-weight and resilient blades into a currently used turbine. For that, a recently developed 3D fiber-metal-laminate (3D-FML) material at Dalhousie University will be used. In comparison to metals that are presently used to form blades, or potentially fiber-reinforced composites, the 3D-FML would […]

As consumer preferences shift from shopping at brick and mortar stores to on-line shopping, there is an increased need for warehouses to use automated systems that fill orders quickly and accurately. This research project will design a warehouse robot that is adaptable to different platform systems and shelving configurations, providing a lighter, faster, and more […]
