The thesis explores a novel wearable reflectance photoplethysmography (PPG) sensor system designed for heart rate measurement in both stationary and dynamic conditions. Emphasizing miniaturization and low power consumption, the device operates on a single PCB with a power draw of approximately 7.5mW. It integrates sensitive electronic circuits and advanced signal processing techniques to enhance robustness against noise and artifacts. Benchmark tests demonstrate its effectiveness, matching the performance of standard heart rate monitors even during movement.

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.
