Patent ID: 11913892
Assignee: NATIONAL INSTITUTE FOR MATERIALS SCIENCE
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A condensation detection element comprising
a condensation detection unit, the condensation detection unit being formed on a first substrate unit, and
a peripheral circuit unit, the peripheral circuit unit being formed on a second substrate unit,
wherein the condensation detection unit comprises a thin wire electrode of a first metal and a thin wire electrode of a second metal, the second metal being different from the first metal,
wherein the thin wire electrode of the first metal and the thin wire electrode of the second metal are disposed in juxtaposition with each other,
wherein the condensation detection unit is configured to detect the presence or absence of water droplet that comes into contact with the thin wire electrode of the first metal and the thin wire electrode of the second metal by a current flowing between the thin wire electrode of the first metal and the thin wire electrode of the second metal,
wherein the peripheral circuit unit comprises at least an output unit that outputs an electrical signal when condensation due to the water droplet is detected, and
wherein the first substrate unit has a higher thermal conductivity and a lower heat capacity than the second substrate unit.
