“…Together with the wide spectrum of sensing technologies above described for breath activity detection, a largely employed alternative is based on the measurement of bio-impedance, that allows gathering information on different vital parameters [39][40][41]. The principle of the impedance plethysmography is based on the recording of the trans-thoracic impedance, which changes proportionally to the volume of inspired air, through electrodes placed on the thoracic surface.…”

“…The principle of the impedance plethysmography is based on the recording of the trans-thoracic impedance, which changes proportionally to the volume of inspired air, through electrodes placed on the thoracic surface. If the trans-thoracic impedance measurement system has enough sensitivity, changes in the impedance related to the cardiac cycle can be detected [41][42][43][44]. This aspect suggests the possibility of designing a simple wearable cardio-respiratory monitoring device based on impedance plethysmography.…”

“…In [41] the authors investigated the feasibility of a simple volt-amperometric bio-impedance measuring device for simultaneous detection of breath and cardiac activities. Starting from measurement of the basal trans-thoracic impedance on several volunteers it was possible to evaluate the sensitivity of the system, showing that the tetrapolar arrangement provides enough resolution for heartbeat detection.…”

Unobtrusive and continuous monitoring of vital signs is becoming more and more important both for patient monitoring in the home environment and for sports activity tracking. Even though many gadgets and clinical systems exist, the need for simple, low-cost and easily applicable solutions still remains, especially in view of a more widespread use within everyone’s reach. The paper presents a fully wearable and wireless sensorized belt, suitable to simultaneously acquire respiratory and cardiac signals employing a single acquisition channel. The adopted method relies on a 50-kHz current injected in the subject thorax through a couple of textile electrodes and on envelope detection of the trans-thoracic voltage acquired from a couple of different embedded electrodes. The resulting signal contains both the baseband electrocardiogram (ECG) signal and the trans-thoracic impedance signal, which encodes respiratory acts. The two signals can be easily separated through suitable filtering and the cardio–respiratory rates extracted. The proposed solution yields performances comparable to those of a spirometer and a two-lead ECG. The whole system, with a realization cost below 100 €, a wireless interface, and several hours (or even days) of autonomy, is a suitable candidate for everyday use, especially if complemented by motion artifact removal techniques, currently under implementation.

“…Reducing the cost could also be achieved by using a low-cost wearable devices for signal acquisition, especially in IoT-based systems [248,249]. Other low-cost devices were used, such as portable ECG monitoring devices in [250,252]. Sanghavi et al [10] proposed an IoT-based remote monitoring system, which includes a Raspberry Pi, Arduino Uno, ECG Sensor and an IoT Cloud for storing and plotting ECG data in real-time.…”

Health monitoring and its related technologies is an attractive research area. The electrocardiogram (ECG) has always been a popular measurement scheme to assess and diagnose cardiovascular diseases (CVDs). The number of ECG monitoring systems in the literature is expanding exponentially. Hence, it is very hard for researchers and healthcare experts to choose, compare, and evaluate systems that serve their needs and fulfill the monitoring requirements. This accentuates the need for a verified reference guiding the design, classification, and analysis of ECG monitoring systems, serving both researchers and professionals in the field. In this paper, we propose a comprehensive, expert-verified taxonomy of ECG monitoring systems and conduct an extensive, systematic review of the literature. This provides evidence-based support for critically understanding ECG monitoring systems’ components, contexts, features, and challenges. Hence, a generic architectural model for ECG monitoring systems is proposed, an extensive analysis of ECG monitoring systems’ value chain is conducted, and a thorough review of the relevant literature, classified against the experts’ taxonomy, is presented, highlighting challenges and current trends. Finally, we identify key challenges and emphasize the importance of smart monitoring systems that leverage new technologies, including deep learning, artificial intelligence (AI), Big Data and Internet of Things (IoT), to provide efficient, cost-aware, and fully connected monitoring systems.

“…Multiple sensorization technologies are being investigated and developed towards their application to the monitoring of the health condition, either in a clinical environment or in wearable devices for remote monitoring at the user's home [4,5]: heart rate variability [6], glucose level in the blood [7], blood pressure [4], temperature [8], physical activity [2], pulse oximetry [9], etc. Among these technologies, bioimpedance takes a prominent place, since it allows providing an insight about the internal processes of the body in a noninvasive way [10,11].…”

This work develops a thorough review of bioimpedance systems for healthcare applications. The basis and fundamentals of bioimpedance measurements are described covering issues ranging from the hardware diagrams to the configurations and designs of the electrodes and from the mathematical models that describe the frequency behavior of the bioimpedance to the sources of noise and artifacts. Bioimpedance applications such as body composition assessment, impedance cardiography (ICG), transthoracic impedance pneumography, electrical impedance tomography (EIT), and skin conductance are described and analyzed. A breakdown of recent advances and future challenges of bioimpedance is also performed, addressing topics such as transducers for biosensors and Lab-on-Chip technology, measurements in implantable systems, characterization of new parameters and substances, and novel bioimpedance applications.
