Title:
IMPEDANCE MEASUREMENT APPARATUS AND IMPEDANCE MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2023/204018
Kind Code:
A1
Abstract:
Provided is a technology capable of measuring the impedance of a biomaterial by using a multi-electrode array device. This impedance measurement apparatus (1) comprises a measurement container (10), a plurality of first electrodes (31), a second electrode (33), a voltage application circuit (43), a current detection circuit (45), and a voltage detection circuit (47). The plurality of first electrodes (31) are disposed in an array shape on a bottom surface inside the measurement container (10). The second electrode (33) is located inside the measurement container (10). The voltage application circuit (43) applies a voltage between each of the first electrodes (31) and the second electrode (33). The current detection circuit (45) detects a current flowing through each of the first electrodes (31). The voltage application circuit (47) detects a voltage between each of the first electrodes (31) and the second electrode (33).
