Smartphone System for Heart Rate and Breathing Rate Estimation

IEEE Open Journal of Instrumentation and Measurement
In this short article, we present a new method to use a smartphone placed unattached on a subject’s chest in the supine position to obtain heartbeat and breathing signals and estimate heart and breathing rates, simultaneously.

HBP-net for robust remote heart rate estimation using heartbeat probability [PDF]

iScience
Summary: Remote photoplethysmography (rPPG) enables contactless heart rate monitoring but remains vulnerable to motion and lighting changes. We address this by reframing heart rate estimation as a heartbeat detection problem, bypassing the need to ...

Enhancing Heart Rate-Based Estimation of Energy Expenditure and Exercise Intensity in Patients Post Stroke [PDF]

Bioengineering
Background: Indirect calorimetry is the gold standard field-testing technique for measuring energy expenditure and exercise intensity based on the volume of oxygen consumed (VO2, mL O2/min).

Active Stacking for Heart Rate Estimation [PDF]

2020 International Joint Conference on Neural Networks (IJCNN), 2020
Heart rate estimation from electrocardiogram signals is very important for the early detection of cardiovascular diseases. However, due to large individual differences and varying electrocardiogram signal quality, there does not exist a single reliable estimation algorithm that works well on all subjects.
