“…The new version of the SoC is included in a new wearable research device and its multimodal capabilities were demonstrated [43]. Consequently, the current versions of the SoC allows bioimpedance, sEMG and sMMG simultaneous recording [50], [51] which reinforces the unobtrusive breathing monitoring and its potential use at home.…”

“…The application of the methods described in the present study requires a multimodal approach to lighten the intrusiveness. In this regard, the acquisition systems are continuously evolving and particularly, the system on chip (SoC) we used [49] currently extended its multimodal feature to fully support the methods we described [50], [51]. The new version of the SoC is included in a new wearable research device and its multimodal capabilities were demonstrated [43].…”

“…It is important to maintain approximately the same position to get comparable results over time and the opposite may introduce variability in biompedance measurements as well as in myographic ones [7], [52]. In this way, the use of patches or vests including the sensors [51], [53] will reduce this variability and improve the reproducibility of the measurements.…”

Chronic Obstructive Pulmonary Disease (COPD) is one of the most common chronic conditions. The current assessment of COPD requires a maximal maneuver during a spirometry test to quantify airflow limitations of patients. Other less invasive measurements such as thoracic bioimpedance and myographic signals have been studied as an alternative to classical methods as they provide information about respiration. Particularly, strong correlations have been shown between thoracic bioimpedance and respiratory volume. The main objective of this study is to investigate bioimpedance and its combination with myographic parameters in COPD patients to assess the applicability in respiratory disease monitoring. We measured bioimpedance, surface electromyography and surface mechanomyography in forty-three COPD patients during an incremental inspiratory threshold loading protocol. We introduced

“…However, amid this transformation, there has been little progress in miniaturizing respiration devices to a suitable form factor for longterm wear and comfort. Research and development of wearables has heavily focused on pulse oximeters and electrocardiograms (ECGs) [20], [26]. The respiration rate and blood O 2 saturation, well-known respiration parameters, are only a subset of respiration parameters.…”

“…The dc-cancellation loop helps to reduce the dc component (the ambient component) in the signal, facilitating a higher ac gain and more dynamic range. The SoC was integrated into a disposable medical-grade encapsulation, as presented in [26] and shown in Figure 7. The wearable health patch incorporates a pulse oximeter, a bioimpedance sensor, a thermometer, and an ECG.…”
