Abstract
The ElectroScience Lab has demonstrated the feasibility to monitor joint flexion and rotation using wearable electrically small loop antennas. Currently, the research uses canonical (cylindrical) tissue models. The objective of this research is to transition cylindrical to anatomical models which will be used to refine the sensors. The anatomical details are varied for diverse individuals and then sensors are optimized for each individual to aid in finding calibration techniques for real life operation. To meet the objectives mentioned, canonical tissue models are replaced with anatomical ones, as readily available in libraries tied to electromagnetic solvers. Then the sensor design is modified to fit the anatomical geometries and simulations are run. The sensor design is optimized for each geometry, and a methodology is created to optimize sensor design for different body parts. Analysis of the results will help find ways to calibrate the sensor in real world conditions.
