A smart scarf for pulse signal monitoring using a flexible pressure nanosensor

Real-time, long-term pulse signal monitoring plays a significant role in monitoring chronic diseases for elder people, pregnant women etc. For users with weak pulse, a carotid pulse signal monitoring system can be appropriate. However, till today no unobtrusive solution is available. Therefore, we suggest a novel flexible and planar pressure nanosensor weaved in a smart scarf system for pulse signal monitoring with better user experience called Smart-SP (smart scarf for pulse signal monitoring system). To our knowledge, this is the first time applying a flexible pressure nanosensor on a wearable carotid pulse monitoring system. To meet the needs of the application, a method is proposed to design the size of the sensor. An interface allows third-party analysis software and provides raw data. A database of pulse signal for diagnostic purposes is set-up. Digital low-pass filter improves the signal accuracy.
