Research Expertise

Description

Declan O'Loughlin's research interests centre around the use of electronics and electromagnetics for biomedical applications. In particular, his research interests include identifying and accounting for variances between patients in bioelectronic medical devices, such as variances between the dielectric properties of tissues of interest and in the size and shape of targets of interest.

Projects

  • Title
    • Optimising the design of microwave hydration monitoring devices
  • Summary
    • This project examines the theoretical foundation for active microwave measurement for hydration status assessment. These devices estimate the electrical properties of the arm which are known to vary with hydration status. While several studies have shown promising results in monitoring dehydration during exercise, results have been based on small studies with limited data and relied on a number of simplifying assumptions regarding the equipment and analysis tools used. The underlying principles are comprehensively examined drawing on the existing evidence and recent literature regarding the natural variability of the electrical properties for reasons other than hydration and the impact of the equipment used to gather the data. These results help determine the minimum standards required to measure and isolate the changes in electrical properties due to hydration alone and the fundamental limitations of the technique.
