The electric impedance measurement channel formed by the voltage detection unit is composed of two, so that the electric current applying unit of each electric channel has a current application electrode and a constant current source, and the voltage detection unit of each electric channel respectively amplifies the voltage detection electrode and the detection voltage. The first channel of the two sets of channels, the first channel is separated from the current applying electrode to be in close contact with the skin surface of the living body, applying a certain weak high frequency current from the constant current source to the living body and the electric current Between the electrodes spaced apart from the electrode for application, the electrode for voltage detection of the first channel is spaced and brought into close contact with the skin surface, thereby providing electrical impregnation. Detects the voltage change according to the change of the switch, and the electrode for voltage application and the electrode for voltage detection of the second channel are spaced apart in the vertical direction from the first channel in the same arrangement as the first channel, and the skin is substantially parallel to the first channel. In close contact with the surface, the current of the second channel is applied to the current applying electrode of the same channel with the weak polarity of opposite polarity of the first channel at the same time. The applied current of the second channel is formed so that a negative impedance sensitivity region is formed, and the magnitude of the applied current of the second channel is adjusted, and the detected voltage during stable breathing that can be obtained between the voltage detection electrodes of the first channel becomes almost zero. By setting only the body movement information from this first channel to obtain information including breathing information from the output of the second channel, and comparing the two output information to obtain pure breathing information only. The multi-electrode type bioelectrical impedance measuring method according to claim. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
