Figure 2. Selected wearable devices with potential applications in COVID-19 and the representative results. (A) Oura smartrings, temperature, HR, HRV and RR were examined prior to and during the reported symptom window, and it was found that many showed similar patterns^[64,76]; (B) Bioimpedance ring, SBP (blue line) and DBP (orange line) estimations with bioimpedance ring sensor in reference to gold-standard Finapres finger BP cuff measurements (gray circles)^[77]; (C) A suprasternal notch-mounted sensing patch for tracking of cardiopulmonary activity during cycling, comparisons of RR and HR determined by the dual-sensing (blue square), single-sensing (red circle) and reference devices (green triangle)^[24].
