ApolloPulse: Electrically Stimulated Wound Healing
11
Sometimes, small cuts and injuries can make it hard for us to do everyday things. They often take up to three weeks to heal, even with special bandages. Conventional dressings provide protection against the elements but are often inadequate in terms of reducing healing time. Our wound dressing employs electrical stimulation to accelerate the healing process using an embedded piezoelectric nanogenerator, which generates electricity through passive daily movements. ApolloPulse aims to make advanced care widely available by leveraging the ease-of-use, scalability, and cost-effectiveness of existing over-the-counter solutions while at the same time dramatically reducing healing time.

NML.ai: Dental Imaging Using Near Infrared Light
12
Traditional x-ray dental imaging is resource intensive, and exposes the patient to ionizing radiation. NML.ai offers a safer, more accessible way for Canadians to monitor their dental health compared to conventional imaging technology. NML.ai is a fully integrated set of tools that work together to detect dental cavities and fractures without a traditional x-ray or dental professional. Near-infrared light is used to backlight teeth; these images are fed to crack detection algorithms that can highlight cracks and cavities in real time. This allows anyone to quickly scan and view the health of their teeth safely and conveniently.

SWEATsens: A sweat-based health monitoring patch
13
Monitoring blood analyte trends is an important aspect of clinical pharmacokinetics, a field that aims to develop individualized dosing regimens and decrease harmful effects of drug therapy. Conventional blood tests fall short for this application since they collect discrete data, providing only a fragmented view of analyte history. However, sweat has been shown to contain many of the same analytes found in blood and offers the advantage of being accessible for continuous, non-invasive monitoring. Based on this correlation, we have designed a wearable sweat-based biosensing patch with integrated sweat stimulation to allow for continuous measurement of analyte levels.

Graphene Field Effect Transistor Biosensor for Detection of Salivary Cortisol Concentration
14
Cortisol, the “stress hormone,” plays a key role in mental health monitoring, stress-related disorder diagnosis, and human performance analysis. Common techniques for measuring cortisol levels are laborious and time-consuming, while real-time stress monitoring techniques are based on questionnaires, which are subjective and cannot produce quantitative results. Our device is a non-invasive point-of-care cortisol biosensor, which employs a graphene field effect transistor to rapidly produce accurate measurements of cortisol concentration in a patient’s saliva. The device’s sensitivity provides precise data to doctors for better diagnoses and its speed saves time and money for patients.
