“…This DRL electrode is usually placed at a distant site, far from the measurement electrodes and thus requires a long wired connection, which may not be convenient for wearable and long-term monitoring systems. Komensky et al [ 31 ] proposed an ECG monitoring system without the DRL circuit, where only two active capacitive sensors were embedded in an elastic chest band. In order to increase and stabilize the input impedance, two anti-parallel connected diodes were used for biasing that has advantages over resistors [ 30 ] of low thermal noise and fast recovery time.…”

Life expectancy in most countries has been increasing continually over the several few decades thanks to significant improvements in medicine, public health, as well as personal and environmental hygiene. However, increased life expectancy combined with falling birth rates are expected to engender a large aging demographic in the near future that would impose significant burdens on the socio-economic structure of these countries. Therefore, it is essential to develop cost-effective, easy-to-use systems for the sake of elderly healthcare and well-being. Remote health monitoring, based on non-invasive and wearable sensors, actuators and modern communication and information technologies offers an efficient and cost-effective solution that allows the elderly to continue to live in their comfortable home environment instead of expensive healthcare facilities. These systems will also allow healthcare personnel to monitor important physiological signs of their patients in real time, assess health conditions and provide feedback from distant facilities. In this paper, we have presented and compared several low-cost and non-invasive health and activity monitoring systems that were reported in recent years. A survey on textile-based sensors that can potentially be used in wearable systems is also presented. Finally, compatibility of several communication technologies as well as future perspectives and research challenges in remote monitoring systems will be discussed.

Demographic change is greatly affecting more and more industrial nations. Therefore, healthcare solutions become increasingly interesting for end-users. However, existing solutions like fitness trackers are mostly worn for a short period of time, i.e. during exercising. Therefore, the implementation of unobtrusive biological sensors via capacitive Electrocardiography (ECG), for application within the user home environment, becomes interesting in the Ambient Assisted Living (AAL) research areas. A capacitive ECG has been developed using an Arduino/Wattuino Uno microcontroller in order to enable the realization of a low cost capacitive ECG System, using existing of-the-shelf components. The developed system comprises an improved version of an earlier prototype of the authors, differing in both hardware and software components used. Furthermore, wireless data transmission quality has been here investigated, in order to enable an unobtrusive implementation of the proposed system when it is used in home environments. In this paper the authors investigate and compare the quality of the measured ECG signal quality under different hardware and software configurations. The results in the paper show that using XBee modules as a secure wireless data transfer solution has a significant deterioration of the measured signal quality. Therefore, solutions are proposed and discussed in the paper to overcome the aforementioned limitations.

“…This very first prototype shows promising results concerning the realization of a low cost, portable, contactless ECG measurement system solution for construction security purposes. Once the improvements are implemented in order to reduce the noise by shielding, as mentioned in [23], this system can be built to a 3 up to 6 lead ECG, in order to enable unobtrusive ECG measurements, according to Einthoven (I, II, III), and Goldberger (aVR, aVL, aVF) [24]. Also for this approach, appropriate Arduino shields are already available on the market [25], which would even decrease the developing cost, if only 1 lead is used, as it is done with the proposed system.…”

Coronary heart disease (CHD), and its different variants, is one of the major reasons of increased death rates in industrialized nations. As the beginning of the disease is symptom free, unconsciousness and sudden death, as well as health related distortions can trigger accidents at construction sites any time. Therefore, there is a need for systems, which can detect such silent symptoms, in order to prevent health related accidents on construction site. Nowadays, most common way to identify first symptoms of CHD is the electrocardiography (ECG). Therefore, in this paper a novel approach for the implementation of a contactless capacitive ECG, which can be straightforwardly embedded in a chair is proposed, in order to enable a pervasive user experience (e.g. while steering heavy machines). The capacitive electrodes were manufactured using ofthe-shelf components, tested and calibrated. The main requirement during the design and development phase was fabrication of a basic low cost capacitive ECG system with wireless connectivity to a platform that could display the corresponding measurements to the user over a display. Such an approach could pave the way for future pervasive sensor fusion, i.e. interfaced with an automated emergency call gateway, in order to enhance the prevention of such diseases, before it is too late for the users. The achieved measurement quality of this contactless system is depicted by comparing measurements between measurements with direct skin contact and with measurements through cloths. The influence of the wireless data transmission using XBee antennas as a communication medium has been investigated, tested, and evaluated.
