The dry electrode-based Health Patch demonstrated high agreement with reference devices for heart rate monitoring (Lin's concordance coefficient 0.98) but marginal agreement for respiratory rate (0.56).

Does a dry electrode-based Health Patch accurately measure heart rate, heart rate variability, and respiration rate compared to reference devices in healthy adults?
The dry-electrode Health Patch provides highly accurate heart rate and heart rate variability monitoring, though respiratory rate accuracy is marginal during exercise due to motion artifacts.
Effect estimate: CCC 0.98 (95% CI 0.98-0.98)
Successful implementation of remote monitoring of vital signs outside of the hospital setting hinges on addressing three crucial unmet needs: longer-term wear, skin comfort and signal quality. Earlier, we developed a Health Patch research platform that uses self-adhesive dry electrodes to measure vital digital biomarkers. Here, we report on the analytical validation for heart rate, heart rate variability and respiration rate. Study design included n = 25 adult participants with data acquisition during a 30-minute exercise protocol involving rest, squats, slow, and fast cycling. The Shimmer3 ECG Unit and Cosmed K5, were reference devices. Data analysis showed good agreement in heart rate and marginal agreement in respiratory rate, with lower agreement towards higher respiratory rates. The Lin's concordance coefficient was 0.98 for heart rate and 0.56 for respiratory rate. Heart rate variability (RMSSD) had a coefficient of 0.85. Participants generally expressed a positive experience with the technology, with some minor irritation from the medical adhesive. The results highlighted potential of this technology for short-to-medium term clinical use for cardiorespiratory health, due to its reliability, accuracy, and compact design. Such technology could become instrumental for remote monitoring providing healthcare professionals with continuous data, remote assessment and enhancing patient outcomes in cardiorespiratory health management.
Wei et al. (Fri,) conducted a observational in Healthy adults (n=25). Health Patch (dry electrode based) vs. Reference devices (Shimmer3 ECG Unit and Cosmed K5) was evaluated on Heart rate measurement agreement (Lin's concordance correlation coefficient) (CCC 0.98, 95% CI 0.98-0.98). The dry electrode-based Health Patch demonstrated high agreement with reference devices for heart rate monitoring (Lin's concordance coefficient 0.98) but marginal agreement for respiratory rate (0.56).
