Abstract This work presents a unique non-invasive method for monitoring glucose levels in blood using planar Yagi–Uda antenna as microwave sensor. The proposed antenna, operating at 5.5 GHz, exhibits directional radiation pattern with peak gain of 6.74 dBi. A low-cost FR4 material size 30 mm × 40 1.6 is used dielectric substrate. human finger phantom, comprising layers skin, fat, blood, and bon...
BACKGROUND Despite increased interest in non-invasive arterial pressure monitoring, the majority of commercially available technologies have failed to satisfy the limits established for the validation of automatic arterial pressure monitoring by the Association for the Advancement of Medical Instrumentation (AAMI). According to the ANSI/AAMI/ISO 81060-2:2013 standards, the group-average accurac...
Accurate continuous direct measurement of the blood pressure is currently available thru direct invasive methods via intravascular needles, and is mostly limited to use during surgical procedures or in the intensive care unit (ICU). Non-invasive methods that are mostly based on auscultation or cuff oscillometric principles do provide relatively accurate measurement of blood pressure. However, t...
Blood pressure (BP) is one of the most important variables evaluated during almost every medical examination. Most national anesthesiology societies recommend BP monitoring at least once every 5 min in anesthetized subjects undergoing surgical procedures. In most cases, BP is monitored non-invasively using oscillometric cuffs. Although the risk of arterial cannulation is not very high, the inva...
