DCU Expo 2023 Final Year Projects

83 171. Air Aware –Wearables for Sensing Personal Exposure to Air Pollution The aimof this project was to develop a reliable, wearable air quality sensor. The device designed is low-cost and low-power and provides the user with a clear understanding of their surrounding air quality. A selection of low-cost sensors have been investigated and eventually refined to develop an air quality system using Arduino technology. The system uses Bluetooth communication to provide users with relevant data relating to their surrounding emissions.

This project investigates the porosity andmechanical properties of four different species of coral, three of which are grown under three different carbonate hardness levels to assess their suitability as bone void fillers. Class Biomedical Engineering (Year 4) Project Area Biomedical Engineering, Materials Testing Project Technology Excel/VB, SPSS Student Name(s) Amy Bourke Email amy.bourke29@mail.dcu.ie Supervisor Dr Owen Clarkin 173. Printing of MagnesiumNanoparticles for Paper Biomedical Sensors This project investigates the printing of magnesium nanoparticles and their application for biomedical sensors. Magnesium nanoparticles have several useful properties including stability, absorptivity, and thermal and electrical conductivity that allow for their wide range of applications including sensing. An ink stampingmethod was used to directly deposit these NPs onto a paper substrate for use as sensing for acetone. Human breathe analysis offers a non-invasive, cheap, and rapidmethod for detecting various volatile organic compounds like acetone for patients with diabetes.
