Recently, Prof. Wenming Zhang from the School of Mechanical Engineering at Shanghai Jiao Tong University collaborated with Prof. Bin Yang at School of Electronic Information and Electrical Engineering to elucidating a fundamentally understanding of piezoelectric dynamic response in arterial pulse for wearable continuous blood pressure monitoring. A paper describing the work, titled “Piezoelectric Dynamics of Arterial Pulse for Wearable Continuous Blood Pressure Monitoring” has been published in Advanced Materials (AM). The first author of this paper is Zhiran Yi. Professors Wenming Zhang and Bin Yang are the corresponding authors.

Piezoelectric dynamics of arterial pulse

In this work, the researchers first elucidate the correlation between piezoelectric pulse waves and blood pressure waves via theoretical, simulation, and experimental analysis of these dynamics. Based on this correlation, they investigated the feasibility of achieving wearable continuous blood pressure monitoring without motion artifacts, using a single piezoelectric sensor. These findings eliminate the controversy over the arterial pulse wave piezoelectric response, and could potentially be used to develop a portable wearable continuous blood pressure monitoring device for the early prevention and daily control of hypertension.
