A flexible PPG sensor patch for measuring pulsations of blood vessels estimating ambulatory blood pressure monitoring (ABPM). The measured quality PPG signals are analyzed to estimate blood pressure (BP), heart rate (HR), blood oxygen (SpO2)atrial fibrillation (A-Fib)avoid motion artifacts. In this way, with subject’s physiological condition apprehended accurately.

The PPG sensing patches with arrayed sensor effectively overcome the inevitable problem of wearable devices what sensing quality is seriously subjected to the motion artifacts of the subject＇s wrist during motionmi-positioning of the patch to the blood vessel. Therefore, the developed patch can measure the fore mentioned target bio-signs with much higher accuracy than commercial health bracelets.

The technology aims to the development of a flexible PPG sensor patch for long term biosensortransfer wireless data to health management systemcloud for biological analysis. The patch is portableeasy to combine with wearable devicehealthcare system for various personal product integration.
