Impedance measurement apparatus and impedance measurement method

Abstract

A technique is provided that allows use of a multielectrode array device to measure the impedances of biomaterials. An impedance measurement apparatus includes a measurement container, a plurality of first electrodes, a second electrode, a voltage application circuit, a current detection circuit, and a voltage detection circuit. The first electrodes are arranged in an array on the bottom surface of the measurement container. The second electrode is located inside the measurement container. The voltage application circuit applies a voltage between each first electrode and the second electrode. The current detection circuit detects current flowing through each first electrode. The voltage detection circuit detects a voltage between each first electrode and the second electrode.
