Effect of Cerebral Artery Stent on the Brain Neurons Activation under the Wireless Charging

Abstract

This study aims to investigate the impact of cerebral artery stent on the brain neuron activation under a wireless charging system. A simplified wireless charger model is developed and positioned in close proximity tothe head region. A cerebral artery stent is modeled and placed inside the brain vessels, and two distinct models are developed, one with the stent and one without it. To determine the electrical potential along a set of nerve fiber, Finite Element Method (FEM) based on the electromagnetic simulation software is employed. A high-frequency waveform is generated and scaled by the stimulus amplitude. Based on the potential distributions and stimulus waveform, the activation thresholds are obtained by setting stimulus amplitudes for the MRG (McIntyre-Richardson-Grill) myelinated fiber models. Results indicate thatthe presence of a cerebral artery stent can cause significant variations in the activation thresholds of brain neurons, up to 22%. As a result, it is imperative to consider the impact of cerebral artery stents on the activation thresholds of brain neurons under a wireless charging.
