Portable Heart Rate Detector Based on Photoplethysmography with Android Programmable Devices for Ubiquitous Health Monitoring System
In this paper, a miniature portable heart rate detector system is implemented by modern hardware ICs and simple sensor circuit with software executable on both PC and Android Lounge Chairs platform.The biosignal is first extracted via photoplethysmography (PPG) principle into electric signal.Then a microprocessor is used to covert biosignal from an
