Abstract
According to various embodiments, an electronic device may comprise: a biological body contact circuit including four electrodes; a current-voltage measurement module including a power supply port, a current measurement port, a first voltage measurement port, a second voltage measurement port, an alternating current signal generator electrically connected to the power supply port, an ammeter electrically connected to the current measurement port, and a voltmeter interposed between and electrically connected to the first voltage measurement port and the second voltage measurement port; a processor; a memory electrically connected to the processor to store the characteristic impedance values of circuit elements interposed between and electrically connected to the current-voltage measurement module and the biological body contact circuit, and to store values for parasitic impedance stemming from parasitic elements existing between the biological body contact circuit and a ground; and a current-voltage path configuration module configured to electrically connect the biological body contact circuit to the power supply port, the current measurement port, the first voltage measurement port, and the second voltage measurement port such that the voltage path and current path of the biological body contact circuit can be changed under control of the processor. Various other embodiments are also possible.
