ABSTRACT
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.
