There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Title: A Novel Multi-Modal, Non- Invasive Sensing System To Automatically Quantify Changes in Extravascular Fluids

Abstract:
The objective of my proposed research is to investigate non-invasive sensing techniques for robustly monitoring changes in extracellular fluid content of biological tissue. The two causes of extracellular fluid alteration that I will research are from intravenous (IV) catheter dislodgment and swelling following ankle injury. First, a robust and miniature system was designed and implemented by researching different integrated circuits, analog front ends, and novel physiology-driven calibration techniques that together increase the system’s accuracy and reduce its size and power consumption. Next, novel methods and algorithms were developed to allow for unobtrusive real-time detection of changes in extracellular fluid content. The system and the methods were validated in human subjects studies and cadaver models for ankle edema tracking, and in human subjects studies for intravenous infiltration detection.
