## Abstract

A wireless transmitted electrocardiogram monitoring device is disclosed. A conductive fabric of the device features on that it is used to be a sensing component with characters of comfort, air permeability, softness, and stretchability thus achieves long-term signal measurement. The processing and transmission method of electrocardiogram signals is characterized in the wireless transmission of the electrocardiogram signals being detected. The signal receiving component (part) is for collecting data, displaying, storage, output and calculation of values. Therefore, a wireless transmitted electrocardiogram monitoring device is applied for long-term monitoring of the physical status of users.
