    A study on the effect of contact pressure during physical activity on photoplethysmographic heart rate measurements by Francesco Scardulla, Leonardo D’Acquisto, Raffaele Colombarini, Sijung Hu, Salvatore Pasta, Diego Bellavia

    Published 2020
    “…Results: The results show that the CP of 54 mmHg provides the most accurate outcome with a Pearson correlation coefficient ranging from 0.81 to 0.95 and a mean average percentage error ranging from 3.8% to 2.4%, based on the physical activity rate. Conclusion: Authors found that changes in the CP have greater effects on PPG-HR signal quality than those deriving from the intensity of the physical activity and specifically, the individual best CP for each subject provided reliable HR measurements even for a high intensity of physical exercise with a Bland–Altman plot within ±11 bpm. …”
