SYSTEM FOR INFERRING DYNAMIC STATE OF SYSTEM TO BE MEASURED USING REDOX POTENTIAL

Document Type and Number:

WIPO Patent Application WO/2023/286864

Kind Code:

A1

Abstract:

[Problem] To provide a system for inferring the dynamic state of a system to be measured, said system for inferring able to acquire data that is stable and correlated with respect to changes in the system to be measured through the ascertainment and management of the operating state of electrodes of the system for inferring the dynamic state of a system to be measured. [Solution] A system 1 for inferring the dynamic state of a system to be measured includes a reference electrode 3, a multi-electrode probe 11 that includes a plurality of working electrodes 5, 7, 9 that are mutually insulated, and a potential measuring/voltage applying unit 13 that measures the redox potential of the reference electrode 3 and one or more working electrodes among the plurality of working electrodes 5, 7, 9, wherein: the multi-electrode probe 11 comprises a tip section 17 that contacts a measurement subject; and the plurality of working electrodes 5, 7, 9 are exposed at least at the tip section 17.
