Abstract :
In this paper, a low-power Heart Beat Rate (HBR) analyzer based on the principle of single reflective Photoplethysmography (PPG) is presented on a MCU platform. It is a non-invasive method of measuring the variation in blood volume in tissues using a light source and a light detector. The PPG signal is amplified and converted to digital format by AFE (Analog Front End) device, MCU takes the signal via SPI communication and performs HBR finding algorithm, afterward sending results to the mobile phone through the Bluetooth 4.0 wireless communication.
