The Kick Ring LL multi-sensor smart ring demonstrated significant correlation with reference standards for measuring heart rate and respiratory rate, indicating potential utility for personalized health monitoring.
With the growing trend towards personalized health, wearable fitness trackers have become a staple of the consumer electronics industry. As the prevalence of such devices booms, the medical community has been compelled to investigate the potential of such devices and explore how they can be used to create positive clinical outcomes. In this report we detail a smart-ring capable of determining heart rate (HR), respiratory rate (RR), blood oxygen saturation (SpO 2) , and temperature. The ring implements a photoplethysmogram (PPG), electrocardiogram (ECG), and thermistor to attain these metrics. After evaluation, significant correlation was found between the experimentally reported HR and RR recordings with their respective standards (p<; 0.05). Experimentally derived SpO 2 had trial-dependent similarities with its reference standards, and temperature measurements were within expected values of normal skin temperature.
