Article Abstract
A system for noncontact ECG recording is proposed that measures the real time electrode-body capacitance concurrently with the ECG as a reference signal for motion artifact reduction. Simultaneous recordings of these two signals from the human body in the presence of electrode motion artifacts are shown and an adaptive least-mean-squares (LMS) filtering algorithm run on these signals is demonstrated to be able to reduce the severity of certain types of electrode motion artifacts.

Continuous monitoring of heart activity, particularly electrocardiogram (ECG) waveforms and heart rate variability (HRV), is essential for the early detection of cardiac diseases. However, conventional wearable ECG systems typically require direct skin contact and external software for signal acquisition and analysis, limiting user comfort and long-term usability. This study presents an unobtrusive contactless bed-embedded system that enables wearable-free, comfortable, and precise monitoring of ECG and HRV without the need for the subject to undress.

Remote photoplethysmography (rPPG) is a technique that enables the extraction of physiological parameters, such as heart rate, from video recordings in a completely non-contact manner. Although widely studied, rPPG research has been hindered by the scarcity of long-duration and complex video datasets recorded in realistic, everyday scenarios. In this work, we present a dataset comprising 10-minute facial video recordings of 26 participants, along with recorded electrocardiograms (ECG) used as a reference signal.

Heart rate (HR) estimation is crucial for early cardiovascular diagnosis, continuous monitoring, and various health applications. While electrocardiography (ECG) remains the gold standard, its discomfort and impracticality for continuous use have spurred the development of non-contact methods like remote photoplethysmography (rPPG). This systematic review (PROSPERO: CRD 42024592157) examines 70 studies to assess the impact of Region of Interest (ROI) selection on HR estimation accuracy.

Tissue Doppler imaging (TDI) mode of echocardiography plays a crucial role in diagnosing several cardiac conditions by recording the myocardial contraction velocities. To mitigate the need of experts for performing echocardiography, several studies have proposed the use of Seismocardiogram as an easier alternative to measure the cardiac timings. However, exact correlation with tissue Doppler measured cardiac velocities has not been explored.

Non-contact electrodes have garnered significant attention as an alternative non-invasive biopotential measurement method that offers advantages such as improved subject comfort and ease of integration into everyday environments. Despite these benefits, ensuring consistent signal quality over time remains a critical challenge, particularly in applications like electrocardiography (ECG), where accuracy and reliability are paramount. This study investigates the temporal stability of signal quality in non-contact biopotential electrodes, with a primary focus on ECG monitoring.
