SENSOR DEVICE
First Claim
1. A sensor device comprising:
- a first electrode including a porous body that has a plurality of holes in at least the vicinity of a surface of the first electrode, the first electrode including a first metallic material in which either a first passivation film is formed on the surface of the first electrode or the first passivation film present on the surface of the first electrode is lost;
a second electrode spaced apart from the first electrode, the second electrode including a porous body that has a plurality of holes in at least the vicinity of a surface of the second electrode; and
a functional element configured to measure a difference in electric potential between the first electrode and the second electrode,a porosity of the first electrode and a porosity of the second electrode being different from each other,the sensor device being configured to measure a state of a site to be measured based on the difference in electric potential as measured by the functional element.

Abstract
A sensor device includes a first electrode, a second electrode, and a functional element. The first electrode includes a porous body having holes in at least the vicinity of a surface of the first electrode, and includes a first metallic material in which either a first passivation film is formed on the surface or the first passivation film present on the surface is lost. The second electrode spaced apart from the first electrode includes a porous body having holes in at least the vicinity of a surface of the second electrode. The functional element is configured to measure a difference in electric potential between the first and second electrodes. A porosity of the first electrode and a porosity of the second electrode are different from each other. The sensor device is configured to measure a state of a site to be measured based on the difference in electric potential.
