DCU Expo 2023 Final Year Projects

67 123. Generation and Characterization of Terahertz (THz)Waves New technologies in communications, space, health, and security will be driven by innovative techniques using wireless signals in the Terahertz (THz) frequency range. In this project, a student will investigate how THz radiation can be generated through the beating of two optical sources on a photodetector and explore how intensity and phase noise affects the quality of the THz signal generated before investigatingmodulation for high-capacity communication links suitable for 6G networking.

The program takes input values for fluid velocity and strain, which determine the rate of cell growth. Additionally, a lattice-basedmodel was used to conduct finite element analysis and obtain strain values. The effect of constant force and displacement on regeneration was also investigated. This study sheds light on the role of mechanical stimuli in bone regeneration and provides insights for potential therapeutic interventions.

Wearable Sensor for VOCDetection Awearable sensor for Volatile Organic Compound (VOC) detection is designed. This project investigates the viability of a wrist-mounted wearable device that tracks the concentration of VOCs coming off the skin using colorimetric sensors. The wearable image sensor uses the onboard camera and transmits the image wirelessly to the cloud for image processing and analysis.
