Abstract
Systems and methods relating to a smart elastic fabric tape are disclosed. For example, a method may include interrogating a sensing mesh using an electrical impedance tomography (EIT) device, wherein the sensing mesh is affixed onto skin nearby a musculoskeletal (MSK) region of interest, wherein the sensing mesh comprises a nanocomposite thin film disposed on elastic fabric tape, and wherein the sensing mesh forms a geometrical pattern on the skin; generating, in real-time, EIT conductivity maps from interrogating the sensing mesh; and generating, in real time, strain distribution and strain directionality data of the MSK region of interest based on the EIT conductivity maps.
