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...
In this paper, a low-cost Heart Beat Variability (HRV) analyzer base on the principle of Photoplethysmography (PPG) is presented on an ultra-low power MCU platform. It is a non-invasive method of measuring the variation in blood volume in tissues using a light source and a detector. Base on the blood variation, the proposed HRV device will be able to calculate the heart beat rate, level of oxygenation...
