Full Analysis of Wearable Textile Sensor for Biomedical Applications: Preliminary Validations Towards a Pre-Clinical Assessment

A full analysis of textile wearable sensor to be adopted for the non-invasive monitoring of diabetes pathology is discussed. Simulation data are collected by adopting a stratified biological material as radiation medium, with an accurate dielectric model for the blood, properly characterizing the variation of its complex permittivity in terms of changes in the glucose concentration. Experimental results on human subject are discussed to demonstrate the validity of simulations. Furthermore, the SAR performance of the proposed sensor configuration are evaluated, and a simple increase in the textile dielectric thickness is applied to guarantee the satisfaction of the imposed maximum levels on humans. Finally, the experimental procedure leading to the preparation of biological phantoms useful for a pre-clinical assessment is described.
