      Lemay, Mathieu; Bertschi, Mattia; Sola, Josep; Renevey, Philippe; Genzoni, Elsa; Proença, Martin; Ferrario, Damien; Braun, Fabian; Parak, Jakub; Korhonen, Ilkka (2020-11-13)
    • Detection of beat-to-beat intervals from wrist photoplethysmography in patients with sinus rhythm and atrial fibrillation after surgery 

      Tarniceriu, Adrian; Harju, Jarkko; Vehkaoja, Antti; Parak, Jakub; Delgado-Gonzalo, Ricard; Renevey, Philippe; Yli-Hankala, Arvi; Korhonen, Ilkka (2018)
      Wrist photoplethysmography (PPG) allows unobtrusive monitoring of the heart rate (HR). PPG is affected by the capillary blood perfusion and the pumping function of the heart, which generally deteriorate with age and due ...
    • Evaluation of accuracy and reliability of PulseOn optical heart rate monitoring device 

      Delgado-Gonzalo, Ricard; Parak, Jakub; Tarniceriu, Adrian; Renevey, Philippe; Bertschi, Mattia; Korhonen, Ilkka (2015)
      PulseOn is a wrist-worn optical heart rate (HR) monitor based on photoplethysmography. It utilizes multiwavelength technology and optimized sensor geometry to monitor blood flow at different depths of skin tissue, and it ...
    • Evaluation of the beat-to-beat detection accuracy of PulseOn wearable optical heart rate monitor 

      Parak, Jakub; Tarniceriu, Adrian; Renevey, Philippe; Bertschi, Mattia; Delgado-Gonzalo, Ricard; Korhonen, Ilkka (2015)
      Heart rate variability (HRV) provides significant information about the health status of an individual. Optical heart rate monitoring is a comfortable alternative to ECG based heart rate monitoring. However, most available ...
    • Physical Activity 

      Delgado-Gonzalo, Ricard; Renevey, Philippe; Lemkaddem, Alia; Lemay, Mathieu; Solà, Josep; Korhonen, Ilkka; Bertschi, Mattia (2017)
      We begin by briefly introducing the basics of the most frequently used sensors in nowadays wearables targeting a profiling of human physical activity: inertial, biopotential, bioimpedance, and optical sensors. The backbone ...
    • Physical Activity 

      Delgado-Gonzalo, Ricard; Renevey, Philippe; Lemkaddem, Alia; Lemay, Mathieu; Solà, Josep; Korhonen, Ilkka; Bertschi, Mattia (2018)
    • Towards 24/7 continuous heart rate monitoring 

      Tarniceriu, Adrian; Parak, Jakub; Renevey, Philippe; Nurmi, Marko; Bertschi, Mattia; Delgado-Gonzalo, Ricard; Korhonen, Ilkka (2016)
      Heart rate (HR) and HR variability (HRV) carry rich information about physical activity, mental and physical load, physiological status, and health of an individual. When combined with activity monitoring and personalized ...
