Heart rate monitors are important devices when studying cardiac function. Commercial wireless heart rate monitors have gained popularity due to their ability to be wearable and portable. These abilities give the device the potential to enter the medical field and to be used for clinical assessment of cardiac function. In order to be considered a medical device, the device must be accurate for a diverse population. Commercial devices have not yet fulfilled this critical criteria. Current wearable heart rate monitors on the market use photoplethysmography (PPG) to detect the human pulse. Since PPG technology depends on light wavelengths to obtain a pulse signal, the ability to identify the best wavelength that works accurately and consistently for the most individuals will open the door for future heart rate monitors to overcome the gap between commercial and medical grade products. This project will compare the accuracy of two popular PPG wavelengths, on a diverse population, using a standard EKG measurement as reference.
