A wearable prototype of reflective sensor for non invasive measurement of heart rate

This research study deals with the design and development of non-invasive and reflectance type (photoplethysmogram) wearable PPG prototype for measuring heart rate.It explains the processing of heart rate from the measured PPG signal.Illustrates the heart rate measurements at different measurement sites.Explains benchmarking of realtime measured heart rate with other standard heart rate measuring units.Presents the heart rate measurements during different actions of swimming when the prototype is mounted on the forhead of swimmer.
