Ballistocardiography and Seismocardiography: A Review of Recent Advances [PDF]

IEEE Journal of Biomedical and Health Informatics, 2015
In the past decade, there has been a resurgence in the field of unobtrusive cardiomechanical assessment, through advancing methods for measuring and interpreting ballistocardiogram (BCG) and seismocardiogram (SCG) signals. Novel instrumentation solutions have enabled BCG and SCG measurement outside of clinical settings, in the home, in the field, and ...

Contactless seismocardiography via deep learning radars [PDF]

Proceedings of the 26th Annual International Conference on Mobile Computing and Networking, 2020
The seismocardiogram (SCG) is a recording of a human heart's mechanical activity. It captures fine-grained cardiovascular events such as the opening and closing of heart valves and the contraction and relaxation of heart chambers. Today, SCG recordings are obtained by strapping an accelerometer at the apex of the heart to measure chest wall vibrations.

Recent Progress in Flexible and Wearable All Organic Photoplethysmography Sensors for SpO2 Monitoring

Advanced Science, Volume 10, Issue 31, November 3, 2023., 2023
The need for continuous, non‐invasive and real‐time monitoring of cardiovascular vital signs is of primary importance. This requires human‐friendly wearable sensor systems that can be easily and conformably integrated onto the human body. Organic electronic devices may fulfill all those properties.

A Novel Broadband Forcecardiography Sensor for Simultaneous Monitoring of Respiration, Infrasonic Cardiac Vibrations and Heart Sounds

Frontiers in Physiology, 2021
The precordial mechanical vibrations generated by cardiac contractions have a rich frequency spectrum. While the lowest frequencies can be palpated, the higher infrasonic frequencies are usually captured by the seismocardiogram (SCG) signal and the ...

Forcecardiography: A Novel Technique to Measure Heart Mechanical Vibrations onto the Chest Wall

Sensors, 2020
This paper presents forcecardiography (FCG), a novel technique to measure local, cardiac-induced vibrations onto the chest wall. Since the 19th century, several techniques have been proposed to detect the mechanical vibrations caused by cardiovascular ...

Non-invasive cardiac kinetic energy distribution: a new marker of heart failure with impaired ejection fraction (KINO-HF)

Frontiers in Cardiovascular Medicine, 2023
BackgroundHeart failure (HF) remains a major cause of mortality, morbidity, and poor quality of life. 44% of HF patients present impaired left ventricular ejection fraction (LVEF). Kinocardiography (KCG) technology combines ballistocardiography (BCG) and
