A ZigBee based wireless EMG/ECG streaming system for the universal interface

This paper deals with a new wireless EMG/ECG real-time streaming system for the universal man-machine interface. The system mainly consists of two components, that is, “the intelligent electrode” and an acquisition host. The intelligent electrode is a small wireless device to be put on the surface of human body to measure EMG or ECG and transmit them out. It can acquire 11-bit digital data with 2 k samples/s speed as well as can transmit all the data to an acquisition host (which is typically a PC) in real time like streaming by using ZigBee wireless technology. In this paper, the author introduces the newest design of the intelligent electrode and some important performances of the prototype devices is verified.
