Evaluation of a textile-based wearable system for the electrocardiogram monitoring in cardiac patients

Abstract

This study indicates that in static condition MagIC has a capability of monitoring cardiac rhythm and arrhythmic events which is comparable with what obtainable by a traditional one-lead ECG recorder. During movement MagIC provides an ECG signal of better quality.

Measurement and Data Transmission Validity of a Multi-Biosensor System for Real-Time Remote Exercise Monitoring Among Cardiac Patients

“…As a caveat, larger biases during simulated sweeping and vacuuming may indicate reduced sensor stability and increased movement artefact during activities requiring substantial upper limb movement. Recent evidence suggests conductive fabric sensors embedded in a textile vest are subject to less movement artefact than traditional adhesive ECG electrodes [43]. Thus the BioHarness compression-fit vest may improve sensor measurement validity; however, it was not publicly available during this experiment and could not be assessed.…”

Fully Textile, PEDOT:PSS Based Electrodes for Wearable ECG Monitoring Systems

“…For ECG signal acquisition, rather than choosing convenient positions to reduce the artifacts, e.g. as in [8] [16], we opted for the single lead standard Holter placement (second lead for 7electrode configuration). In this configuration, the negative electrode is placed close to the right clavicle (lateral to the midclavicular line) and the positive one is placed close to the 6 th intercostal space on the anterior axillary line.…”

“…The application of textile electrodes embedded into smart garments for ECG monitoring ranges from elderly monitoring (heart failure prevention) [5] to tele-health [6], including sport or extreme conditions [6], infants monitoring [7] and clinical use [8] [9]. The same technology has also been extended to nongarment textiles, like those on household furniture, for similar purposes [9] [10], or to produce headbands to record other electrophysiological signals such as EMG [11] and EEG [12] [13].…”

“…Dry textile electrodes can overcome these problems, with the drawback of a higher contact impedance [16], due to the material but also to the irregular electrode surface [17]. Most dry textile electrodes reported in the recent literature exhibit high skin contact impedance, which either limits their use when very small signals must be recorded [12] or poses doubts about the achievable signal quality [18] [19], even though some examples of clinically acceptable results have been recently provided [8]. These textile electrodes are usually based on fine metal wires, or metal coated yarns, woven or stitched with conventional textile fibers.…”

Fully:Textile Polymer:Based ECG Electrodes: Overcoming the Limits of Metal:Based Textiles

“…Despite such premises, the application in clinical settings is still far from being widespread, even though some clinical studies appeared [7]. Originally developed to replace off-the-shelf disposable gelled Ag/AgCl electrodes, the gold standard for clinical and short-term recording but limited by short operating time and poor comfort, traditional textile electrodes used without any conductive hydrogel failed to provide an effective way to access high-quality ECG signal [8].…”
