“…Instead, the winding optimizer uses macroscopic strategies for PNS reduction, such as bending the Bfield away from the torso and redirecting it to smaller body parts (such as the extremities or the head) where they lead to smaller E-field amplitudes, and therefore reduced PNS propensity. In reality, there are of course many sources of PNS threshold variability among subjects, including body shapes, tissue composition (such as body fat percentage) [19,59], varying dielectric tissue properties, and anatomical and physiological details of the nerve fibers (such as level of myelination, node of Ranvier spacing, etc) [19]. We hypothesize that this variability does not significantly impair the PNS improvements of our optimized windings, as we are aiming for relative threshold improvements (i.e., increasing the PNS threshold averaged over a large population).…”
