Revolutionizing smartphone gyrocardiography for heart rate monitoring: overcoming clinical validation hurdles [PDF]
Frontiers in Cardiovascular Medicine, 2023 Accurate heart rate (HR) measurement is crucial for optimal cardiac health, and while conventional methods such as electrocardiography and photoplethysmography are widely used for continuous daily monitoring, they may face practical limitations due to their dependence on external sensors and susceptibility to motion artifacts.

Heartbeat Detection in Gyrocardiography Signals without Concurrent ECG Tracings [PDF]
Sensors, 2023 A heartbeat generates tiny mechanical vibrations, mainly due to the opening and closing of heart valves. These vibrations can be recorded by accelerometers and gyroscopes applied on a subject’s chest. In particular, the local 3D linear accelerations and 3D angular velocities of the chest wall are referred to as seismocardiograms (SCG) and ...
