Electrocardiogram (ECG) filtering algorithms for real-time ambulatory applications in harsh environments

The electrical activity of the heart i.e. ECG, can convey a lot of useful information about an individual’s health and psychological states. Wearable devices recording ECG signals can help monitor the physical health of soldiers remotely and help make critical decisions like casualty detection, remote triage, and medical management. However, ECG signal quality from these devices is often poor due to various problems such as sensor or body movement, environmental disturbances etc.

High purity diamond deposition system

Synthetic diamond allows to exploit technologically relevant properties at much more affordable costs than based on natural diamond. While early applications related to the extraordinary hardness of diamond, more recent applications target the outstanding heat conductivity and dedicated point defects that allow for the control of individual paramagnetic states. This has extended the requirements for the controlled growth beyond the requirements for a high-quality bulk structure towards the engineering of surface passivation and defect state populations via dopants.

Identification des protéines cellulaires impliquées dans l'effet antiviral des polymères d'acides nucléiques (NAPs) lors d'une infection par le virus de l'hépatite B (VHB) (PARTIE-II)

L’hépatite B est une affection hépatique causée par le virus de l'hépatite B (VHB) qui peut évoluer sous une forme chronique et exposer les malades à un risque important de cirrhose et/ou de cancer hépatique. Malgré un vaccin efficace, le VHB affecte de façon chronique plus de 270 millions de personnes et cause plus de 800 000 décès par année. Récemment, l’entreprise montréalaise Replicor a procédé à l’élaboration d’un traitement novateur basé sur l’utilisation de « polymère d’acides nucléiques » (NAPs).

Développement d'un procédé électrochimique pour le traitement à la source des eaux usées phytosanitaires

Les produits phytosanitaires utilisés en agriculture, pour lutter contre les espèces nuisibles et les adventices sont devenus essentiels pour une agriculture performante. Cependant, la présence de ces composés (herbicides, insecticides et fongicides) dans les eaux est à prendre en considération en raison de leur toxicité potentielle pour l’homme, pour la faune et la flore du milieu aquatique contaminées.

COVID-19 Prevention: Hybrid Polymer/Photoactive Ceramic Self-Disinfecting Coating

This twelve-month project aims to understand and propose a practical solution to prevent transmission of COVID-19 from contact with contaminated surfaces. It addresses a challenge of crucial importance for Canada and for Bioastra Technologies, a Canadian company specialising in smart materials for health, robotics and environmental applications. BioAstra was recently designated as an "essential service" by the Quebec government to repurpose existing smart coating and smart wearables technology towards the fight against COVID-19.

Testing and optimizing the performance of a digital micromirror device (DMD) for mid-wavelength infrared imaging

Mass fever screening, as the most effective way to control the spread of these pandemic diseases, is vital to reduce the impact of COVID-19 to Canada. However, existing methods for mass fever screening is largely inefficient due to limited sensitivity in temperature measurement, which is attributed to easy interference by ambient parameters, low resolution, and incorrect ways of deployment.

Real-time acoustic detection on mobile devices to support the deaf and hard of hearing with situational awareness

Hearing loss individuals face apparent as well as subtle, systematic, and safety challenges every day in a world predicated on hearing. Traditional hearing assistive solutions are not readily available in some environments. Hence, Lisnen is exploring opportunities to leverage available tools, such as mobile devices, to act as a hearing assistive device to provide situational awareness. These devices will identify relevant and vital sounds, both indoors and outdoors spaces using deep learning models.

Development and Optimization of Bio-electro coagulation process for ground and surface water treatment

Ground water is the principal drinking water source in North America and approximately 150 million people relies on ground water for their domestic supply. Groundwater contamination occurs as a direct or indirect result of human or animal waste ingress to groundwater resources. The anthropogenic activity resulted in the contamination of surface and ground water with metals and other inorganic contaminates. The presence of metals, organic and inorganic contaminants in aquatic environment (ground and surface water) represent a health risk to human, animals and aquatic organism.

Antiviral activity of biosurfactants against SARS-CoV-2 and other enveloped viruses

The scope of the proposed project is to formalize our understanding on the antiviral capacity of our natural bioproducts by testing them against SARS-CoV-2 and other enveloped viruses, such as influenza. This development will enable us to then propose our Dispersa technology in an antiviral capacity, not only for sanitation of skin and surfaces - but also an added application of antiviral coating for medical equipment and infrastructure. We hope to contribute to COVID-19 efforts by leveraging our innovation to provide natural solutions to society during this global crisis.

Development of CuO-doped phosphate glass in Hydrogel matrix for bone regeneration

In the framework of developing of low-cost bones regeneration implant, bioactive copper oxide phosphate glasses/HA-Chitosan hydrogel are to be investigated to determine optimal formulation producing a HA/hydrogel matrix with structure similar to that of natural bone.
