Flexible PPG sensor patch
Innovations Flexible PPG sensor patch
  • Technology Introduction
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) and atrial fibrillation (A-Fib) and avoid motion artifacts. In this way, with subject’s physiological condition apprehended accurately.
  • Scientific Innovation
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 motion and mi-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.
  • This technology won the Futuretech Breakthrough Award in 2019 Future Tech Expo.
