Measuring body composition is significant in the diagnosis, monitoring and management of fluid distribution and muscle and fat mass. Traditional methods of measuring body composition are timely and expensive, whereas bioimpedance offers a quick and cost effective alternative. The current bioimpedance measurement devices however, are not always user-friendly and often lack the ability to perform continuous measurements. Therefore the objective of my research is to develop a device that is user-friendly, and can continuously measure bioimpedance of the leg through a convenient electronic textile sock. To achieve this, first we performed a preliminary analysis on bioimpedance data of several hundred individuals and compared various bioimpedance regression models based on the gold standard method for measuring body composition. Consequently, we proposed a new model which has higher accuracy compared to the previous models proposed in the literature. The next steps include the testing of dry electrodes to identify the ideal configuration to maximize signal-to-noise ratio and the design of the bioimpedance system itself. The system will fill the need for a practical tool that is portable and easy to use to measure fluid volume in the leg. The proposed system can have a significant clinical role in monitoring edema and body composition in the leg.
