88 168. Real Time Radon Detector Radon is an inert, odorless, colorless, radioactive gas. The Isotope Rn-222 is the secondmost common cause of Lung Cancer in Ireland. The current forms of Radon measurement devices available to the average consumer are accurate but are not affordable to everyone or can take long periods of time to produce results. This project aims to develop a low-cost, real time solution. This solution could increase accessibility of Radon measurement to those who wish tomeasure Radon levels in their area but cannot afford a detector currently. This solution could also be used in educational settings to increase awareness of Radon and its impact on the lives of those living in areas of high Radon concentration.

A 3Dmulti-layered skin model is developed, incorporating hyperelastic material properties for the skin layers. The study explores how pre-tension affects tissue deformation and stress distribution, highlighting its role in altering the mechanical response of the skin during needle insertion. The findings aim to improve predictive modelling of skin-needle interactions by considering the realistic effects of pre-tension, thereby optimisingmedical procedures such as subcutaneous drug delivery. A better understanding of pre-tension’s impact on skin mechanics will contribute to advancements in minimally invasive procedures, ultimately enhancing patient comfort.

This robot armwhich utilises servomotors and a stepper motor, currently lacks a dedicated control method and its practical use is limited. To address this, a software application is implemented to provide an intuitive and seamless interaction platform. AGraphical User Interface, developed using Qt and Python, facilitates real-time communication with an ESP32 microcontroller via USB serial. The ESP32 executes commands to control the motors, while the GUI supports multiple input methods, including graphical sliders, keyboard inputs, and game controllers. This project makes the robotic armmore accessible and versatile for a range of applications.
