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.
