Title:
DEGRADATION EVALUATION SENSOR, DEGRADATION EVALUATION METHOD, AND DEGRADATION EVALUATION DEVICE
Document Type and Number:
Japanese Patent JP2023117523
Kind Code:
A
Abstract:
To provide a sensor that can be used in measuring an index value pertaining to the degradation of a coated object.SOLUTION: The present invention is a degradation evaluation sensor comprising: a flexible ionic conductor (n) which is attachable/removable from a resin body (f) which is in close contact with a metal body (m); an electrode (e) which is tightened to the ionic conductor, and a holding body (h) which is removably adhered to the resin body and capable of holding the ionic conductor and the electrode on the resin body. Using this sensor makes it possible to measure an index value (e.g., impedance or tanδ frequency characteristic) pertaining to the degradation of the object (P) to be evaluated that includes the resin body. The ionic conductor is, for example, a sponge impregnated with a solid polymer electrolyte or a liquid electrolyte. Index value measurement may be carried out using two pairs of sensor units (S1, S2), each of which has the ionic conductor and the electrode disposed on the resin body with a space therebetween.SELECTED DRAWING: Figure 1A
