This kind of micro electric activity spreads along the conductor of men to the surface of the body, thus we can get the ECG by electrodes (sensors).
这种微观的电活动沿人体这一容积导体传至体表，通过电极传感器便可得到心电波形。

Under the control of micro-computer, the resistivity of the formation measured is derived from the main current and the midpoint potential of the two monitor electrodes.
整套仪器的工作均在微机的控制之下进行，通过测量主电流和两监督电极中点的电位而获得被测地层的电阻率。

The ICNFRS are composed of micro-electrodes, Signal Detecting Circuits (SDC), Signal Processing Circuits (SPC) and Functional Electrical Stimulating (FES) circuits.
