Towards the Development of Wearable Blood Pressure Sensors: A Photo-Plethysmograph Approach Using Conducting Polymer Actuators

摘要

Blood pressure is among the most critical measures that physicians use for broad clinical applications. Yet, continuous blood pressure measurement is available only for hospital settings and other limited cases. As of today, there is no wearable sensor that can measure blood pressure continuously and reliably as well as for a long period of time. Bulky wrist-band type sensors and arm cuff type sensors are practically infeasible to wear for a long time, due to interference with patients' daily activities. It is expected that development of truly wearable blood pressure (BP) sensors will have a significant impact upon broad health monitoring applications.
