Description

Knit-based conductive textile with suppressed electrode elongation due to wear and smart wear system using the same The present invention relates to a conductive textile and a smart wear system using the same. Monitoring the body's biosignals using electronic devices is a convenient and effective method for verifying, maintaining, and managing a person's biological state. Recently, there has been active development of technologies that provide convenience functions naturally during daily life by wearing electronic devices, rather than holding and managing them in the hand, such as wearable devices. Representative commercially available wearable devices include the forms of watches and rings. However, these are characterized as accessories worn in addition to other items. In contrast, smart wear in the form of clothing or garments is attracting attention because it can detect or respond to external signals while being worn at all times. Meanwhile, the biosignals that monitoring devices intend to measure vary greatly depending on their purpose. Representative examples of biosignals include electromyography (EMG), electrocardiogram (ECG), heart rate, blood pressure, skin conductivity, and body temperature.
