Abstract
Bioimpedance is an electrical property, which is measured to indicate related parameters and diagnose several diseases of the body. The heart pulsatile is a blood flow with periodic variations as a result of heart beats. The main objective of this article is studying the effect of the heart pulsatile on the measurements of artery bioimpedance. However, neglecting the heart pulsatile leads to error in calculations of many applications based on artery bioimpedance measurement such as glucose monitoring, stenosis, and cholesterol detection. Furthermore, the studying of the heart pulsatile effect could be developed to measure the heart rate as a novel method based on bioimpedance phenomena. A simple model of electrodes and composite layers (skin, fat, muscle, and artery) is simulated using COMSOL. In this work, a model of noninvasive electrodes for measuring an artery bioimpedance is described to show the best method to take into consideration the effect of heart pulsatile.
