  1. 1. Heart rate estimation from wrist-PPG signals in activity by deep learning methods

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Marie-Ange Stefanos; [2023]
    Nyckelord :Deep Learning; Medical Data; Signal Processing; Heart Rate Estimation; Wrist Photoplethysmography; Djup lärning; Medicinska Data; Signalbehandling; Pulsuppskattning; Handledsfotopletysmograf;

    Sammanfattning : In the context of health improving, the measurement of vital parameters such as heart rate (HR) can provide solutions for health monitoring, prevention and screening for certain chronic diseases. Among the different technologies for HR measuring, photoplethysmography (PPG) technique embedded in smart watches is the most commonly used in the field of consumer electronics since it is comfortable and does not require any user intervention.

    Sammanfattning : In this master's thesis the ability to estimate the respiratory frequency from heart rate variability measurement is analyzed. The goal was to implement a solution that is easily transferable to real time. LÄS MER

  4. 3. Real time non-invasive estimation of oxygen uptake using smartphones

    Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologi

    Författare :Arvid Lund; [2023]
    Nyckelord :Oxygen uptake; Acceleration; Smartphone; Estimation; Health; Technology and Engineering;

    Sammanfattning : Oxygen uptake is a great indicator of cardiopulmonary health but requires spe- cialized equipment and is time consuming to measure. There are ways to estimate oxygen uptake based on other factors such as heart rate and acceleration. LÄS MER

  5. 4. Heart Rate Measurement using a 60 GHz Pulsed Coherent Radar Sensor

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Melina Al Nasser; Linn Gromert; [2022]
    Nyckelord :Signal processing; EKG; Heart rate; Radar sensor; Neural network; Acconeer; Technology and Engineering;

    Sammanfattning : Heart rate is today measured in various ways, but they all include contact with the skin. Measuring heart rate contactless would be a more efficient method in healthcare and would also benefit people suffering from skin problems. It has been proven that it is possible to use radar to measure heart rate. LÄS MER

  7. 5. Robust heart rate estimation from a smartphone camera

    Kandidat-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :Ammar Darwesh; Miran Harivandy; [2022]
    Nyckelord :HR calculation; PPG; Photoplethysmography; HR calculation in smartphone;

    Sammanfattning : When it comes to calculating physical activity, nowadays a wide variety of tools is at our disposal.The phones used daily incorporate functions that calculate, for example, the number of steps taken throughout the day. Using the tools to set personal goals or to review which physical properties deviate. LÄS MER
