Daily pulsation measurements are useful for managing various health conditions. In this article, we discuss the development of a technique that uses wearable devices for measuring pulsations using bioimpedance. The pulsations from the study subject were measured using wrist-attached electrodes in the MHz band. Results showed that pulsations can be measured based on the changes in the bioimpedance under all studied conditions. Moreover, the bioimpedance changed with the pulsations even in discontinuous measurements. These results show the feasibility of bioimpedance-based plethysmogram detection using the MHz band. © 2021 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.

使用 MHz 频段的基于生物阻抗的体积描记图检测

每日脉搏测量可用于管理各种健康状况。在本文中，我们将讨论使用可穿戴设备通过生物阻抗测量脉动的技术的开发。来自研究对象的脉动是使用 MHz 频段的腕带电极测量的。结果表明，可以根据所有研究条件下生物阻抗的变化来测量脉动。此外，即使在不连续的测量中，生物阻抗也会随着脉动而变化。这些结果显示了使用 MHz 频带进行基于生物阻抗的体积描记检测的可行性。© 2021 日本电气工程师学会。由 Wiley Periodicals LLC 出版。
