Abstract

The possibility and feasibility of using the single-layer flat-coil-oscillator (SFCO) technology-based vibration and vibro-acoustic sensors in diagnostic devices and biomedical studies of the cardiovascular system are discussed in this paper. Using an example of recording pulse waves of left carotid artery and their analysis, the information content of the data recorded by these sensors in a number of cases is shown-assessment of age-related changes in the stiffness of the vascular wall, assessment of the dynamics of systolic volume, reflecting myocardial contractility, and rhythm disturbance (extra-systole and arrhythmia). These sensors are shown to be promising in recording heart sounds due to their high sensitivity. The possibility of assessing the dynamics of relaxation of the cardiovascular system after exercise (stress test) is shown. The advantages of using SFCO vibration and vibro-acoustic sensors are high sensitivity, ease of use, and no need to train specialists. These advantages open new perspectives for their implementation in mobile wearable "smart" devices for individual monitoring.

基于单层扁平线圈振荡器技术的振动和振动声传感器在心血管系统医学和生物学研究中的适用性:颈动脉脉搏波配准的优势和前景。
本文讨论了基于单层扁平线圈振荡器(SFCO)技术的振动和振动声传感器在心血管系统诊断设备和生物医学研究中的可能性和可行性。通过对左颈动脉脉搏波的记录和分析,展示了这些传感器在许多情况下记录的数据的信息内容-评估血管壁硬度的年龄相关变化,评估收缩容量的动态,反映心肌收缩性,以及节律障碍(收缩外和心律失常)。由于其高灵敏度,这些传感器在记录心音方面被证明是有希望的。显示了评估运动后心血管系统放松动态的可能性(压力测试)。使用SFCO振动和振动声传感器的优点是灵敏度高,使用方便,不需要培训专家。这些优势为它们在个人监测的移动可穿戴“智能”设备中的应用开辟了新的视角。
