Clinical Validation of a Wearable Piezoelectric Blood‐Pressure Sensor for Continuous Health Monitoring

Abstract Wearable blood‐pressure sensors have recently attracted attention as healthcare devices for continuous non‐invasive arterial pressure (CNAP) monitoring. However, the accuracy of wearable blood‐pressure (BP) monitoring devices has been controversial due to the low signal quality of sensors, the absence of an accurate transfer function to convert the sensor signals into BP values, and the lack of clinical validation regarding measurement precision. Here, a wearable piezoelectric blood‐pressure sensor (WPBPS) is reported, which achieves a high normalized sensitivity (0.062 kPa −1 ), and fast response time (23 ms) for CNAP monitoring. The transfer function of a linear regression model is designed,…
