A Study On The Development Of A Heart Rate Monitoring System To Determine Its Accuracy And Effectiveness

Abstract

Heart rate monitoring systems are valuable tools in both medical and fitness settings since they provide crucial data for health assessment and activity optimization. The study's goal was to build and execute a heart rate monitoring system that used modern sensors and signal processing techniques, as well as to test the system's accuracy against a known heart rate measurement instrument. The development process involves System Design, which incorporates optical and electrical sensors to gather heart rate data, as well as a microprocessor for signal processing and transmission. The next step is prototype development, which focuses on portability and user comfort. Testing and validation entail using human participants to compare system results to those from clinically approved heart rate monitors. Various activities, such as relaxing, walking, and severe activity, are used to evaluate performance in various settings. The designed heart rate monitoring system has good accuracy, with an average deviation of less than 5% compared to reference devices. Accuracy was constant throughout activities, with little differences noted during high-intensity exercise. The device tracked heart rate variations in real time, providing accurate data for both short- and long-term monitoring. The study emphasizes the relevance of sensor quality and signal processing in creating accurate heart rate monitoring devices. While the system performed admirably in most situations, further refinements could increase accuracy during high physical activity. The use of machine learning techniques for adaptive filtering and noise reduction holds promise for future iterations.
