Wearable Pulse Wave Sensor and Interface for Real-Time Dynamic Blood Pressure Monitoring

Real-time dynamic blood pressure (BP) monitoring can facilitate predicting and managing cardiovascular diseases such as hypertension and stroke. Pulse wave that contains critical and ample information on BP is a key vital sign to monitor and thus an epidemical wearable device enabling realtime acquisition of pulse wave becomes critical. In this work, we introduce a flexible and wearable piezoelectric array sensor and a thin-film transistor-based sensor interface aiming for efficient acquisition of redundant pulse waveforms sufficient for extracting BPs using deep learning method. The proposed pulse wave sensor offers a viable approach to realtime cardiovascular monitoring.
