Wearable monitoring system is designed for skin stimulation of conductive adhesive, prolonged physiological monitoring and biocompatibility, whose core is fabric electrodes and it can feedback physiological status by analysis of abnormal electrocardiogram (ECG). Fabric electrode is a sensor to collect biological signals based on textile materials including signals acquisition, processing systems and information feedback platform and so on. In this paper, the design methods and classification of medical electrodes would be introduced. It also sorted out the principle of biological electrical signals, the design methods and characteristics of different material and different structure electrodes from the point of dry electrodes and wet electrodes. There are many methods that can be used to prepare fabric electrodes. They are mainly metal plating, conductive polymer coating, magnetron sputtering, gas phase deposition and impregnation. Besides, they select the appropriate substrate, conductive medium and composite way to get light fabric electrodes which have high conductivity, good conformability. From the perspective of biological signal acquisition by fabric electrodes, this paper also sorted out the influence and approaches of biological signals and the way to feedback the physiological condition of human. As a new generation of bio-signal acquisition material, fabric electrode has met the requirements of the development of modern medicine. Fabric electrode is different from traditional conductive materials in the characteristics of comfort, intelligence, convenience, accuracy and so on.

“…Human body is composed of cell membrane which is a kind of semi-permeable membrane. The principle of semipermeable membrane is that only a certain kind of ions can go through it in a certain state [1]. It's known that there are a series of physiological and chemical changes in the body when a man is in motion.…”

Due to its convenience, wear ability, affinity, continuously monitoring biological signal, etc., fabric electrodes used in biological signal acquisition attracted more and more interest from researchers around the world. Fabric electrode is a kind of intelligent textiles, and its application is very prominent in biological signal acquisition, supercapacitors and ECG (electric signal) monitoring. There are many methods that can be used to prepare fabric electrodes. They are mainly metal plating, conductive polymer coating, magnetron sputtering, and gas phase deposition and impregnation. Besides, they select the appropriate substrate, conductive medium and composite way to get light fabric electrodes which have high conductivity and good conformability. Since the conductive properties of conductive polymers are weaker than those of metal, conductive polymer must undergo protonic acid doping. They can be polythiophene, polypyrrole, polyaniline, etc. However, at present, researchers commit more studies to metal or carbon-based electrodes. For example, a layer of silver film is platted on the fabric by magnetron sputtering to increase its conductivity. In this paper, the development of fabric electrodes was studied from several aspects, namely, the generation of biological signals, the overall design of the wearable monitoring systems, its classification, conductive principles, preparation of fabric electrode and application.

“…This integrated circuit (IC) embeds several features commonly used in ECG applications, thus reducing the requirements of external circuitry, allowing to save board area and to reduce power consumption. Chips of this family have been already adopted in previous works in the literature, such as the ADS1198 in [7], where a preprocessing stage is designed for the needs of the test with textile electrodes, and the acquisition is controlled directly by a LabView interface, and in [8] where an ADS1298-based preprocessing system for ECG acquisition is presented.…”

The issue of biopotentials acquisition with surface electrodes has been studied for several years, during which a number of reliable techniques have been developed. Nowadays, they form a solid background of practices exploited in every commercially available biopotential acquisition module. Nevertheless, in some application fields where signal processing of the acquired signals is controversial, due to the lack of a deep understanding of the underlying physical aspects, there is the need to test several recording setups to define the one producing the best results. In fact, signal acquisition has strong influence on the signal processing techniques that can be deployed to post-process the data. Non-invasive fetal electrocardiography (ECG) is one of those field. In order to enable the investigation of the aspects connected with the signal acquisition, we developed a custom biopotential acquisition unit, with configurable measurement setup. It is intrinsically general purpose, but has been conceived to support studies on non-invasive fetal ECG on the animal model. Based on the ADS1298 analog front-end, the developed system achieves comparable performance with respect to commercial systems for physiological research opening to the first animals studies about the influence of the acquisition setup on the effectiveness of the signal processing algorithms for fetal ECG extraction
