This article describes a multimodal cardiovascular information measurement method using a wearable device composed of piezoelectric transducers. Cardiovascular diseases are increasing with the aging population, and they constitute a significant portion of the causes of death and long-term care. In recent years, daily-life monitoring using wearable sensor devices has attracted particular attention for the prevention and early detection of cardiovascular diseases. However, recent wearable devices can only measure limited cardiovascular information such as the heart rate. In contrast, the proposed method can simultaneously measure heart rate variability, pulse wave propagation velocity, and blood flow velocity using only a piezoelectric transducer array.
