<P>PROBLEM TO BE SOLVED: To provide a measuring apparatus and its measuring method for biological impedances. <P>SOLUTION: The measuring apparatus for biological impedances includes: a plurality of electrodes which are brought into contact with body areas of a subject; an input signal forming section which forms an input electric signal for measuring the biological impedance, and feeds the input electric signal to a driving electrode from among the plurality of the electrodes; an impedance measuring section which measures the biological impedance from an output electric signal which is output through a sensing electrode from among the plurality of the electrodes; and a display section which displays the measuring state and results. The input signal forming section includes a modulating section which modulates signals, and the impedance measuring section includes a demodulating section which demodulates the output electric signal by a method corresponding to the modulating section. The measuring apparatus for biological impedances modulates the driving signal which is applied, and demodulates the measuring signal which is output, and therefore, can effectively remove influences by noises which are applied from a living body. <P>COPYRIGHT: (C)2011,JPO&INPIT |
