英文摘要：

In view of the complexity and particularity of underground’s channel environment, in this paper the ECG sensor node is designed and accomplished on the basis of low power consumption and strong penetration. By comparing module selection options for the sensor node, the design scheme is proposed using AD8232 for ECG signal acquisition chip, STM32F103C8T6 for MCU and SI4463 for wireless transceiver chip. The study expounds the software design and low-power strategy. In the end, the power consumption and performance of the node are put to test and the corresponding analysis is presented.
