Graphene Quantum Dots for an Electroluminescent LED

15

Quantum dot (QD) technology is a promising area of innovation within the global display industry. Existing QLED displays use QDs in a photoluminescent capacity, requiring an LED backlight. The development of electroluminescent QDs would allow for greater efficiency, better colour accuracy, wider viewing angles and perfect black levels. Current displays suffer from bottlenecks imposed by blue LEDs. Blue LEDs degrade more rapidly and perform poorly compared to their red and green counterparts. Our prototype will demonstrate a functional graphene-based blue emitting QD-LED. To be successful, this device will be electroluminescent and act to mitigate issues plaguing standard blue LEDs.

SenUV: Full-Spectrum Machine-Learning Aided UV Sensor

16

Current UV detection methods are either poor and affordable or expensive and not available to the average consumer. With increased UVC lamp use due to COVID-19 along with everyday UV exposure, we felt it necessary to investigate and prepare an affordable detection method for concerned parents and individuals. Our design is a small wearable UV sensor coupled with a smartphone application that provides information about current exposure in the UVABC range as well as previous exposure trends. It combines integrated circuit thin-film technologies and machine-learning algorithms to detect all three subtypes of UV to a high degree of accuracy.

Solé: Textile-Integrated Flexible Organic Solar Cells

17

There are currently no established portable, durable, and renewable energy sources designed to be used while on an off-grid outdoor excursion. SOLÉ has designed an easily installable, flexible, weather proofed organic solar cell charger for outdoor activities such as camping. Our design has a unique focus on adhesion to textiles such as tents and tarps; It is able to conform to uneven surfaces, and is easy to store alongside the fabric it is installed on. The installation process is quick, straightforward, and only requires common household tools. The device can be retrofitted onto a variety of outdoor products.

Carbon Nanotube Ink Capacitive Pressure Sensor for

Overpronation Treatment

18

Overpronation is a flatness of the foot which affects an estimated three out of four people. The condition causes an abnormal gait and increases the risk of injuries such as plantar fasciitis. To aid diagnosis and treatment of this common condition, a flexible pressure sensor was designed to capture the pressures throughout the sole of the foot. Using two conductive carbon nanotube (CNT) layers with vinyl in between, a grid of capacitors was created which allows for the detection of a wide range of pressures. The sensor is also sweat-proof, flexible and durable: ideal for use in a shoe.
