Abstract: As a conventional antifouling measure to prevent adherence of aquatic organisms to a submersible sensor unit, a grease containing a stimulant, such as mustard, capable of repelling aquatic organisms is applied onto a sensing part thereof, thereby preventing adherence of the aquatic organisms. However, the irritant-containing grease applied onto the sensing part will come off within one to two months, resulting in disappearance of its effect. Thus, it is necessary to perform work of pulling up the submersible sensor unit and re-applying the grease, in each case. The present invention provides a water flow resistant submersible sensor unit which comprises an aquatic organism adherence preventive film capable of preventing adherence of aquatic organisms even when used in the submersible sensor unit for about half a year, almost without involving any underwater movement, and capable of, after use, being easily peeled off from the submersible sensor unit.

Abstract: A gas sensor includes: a gas-sensitive body layer disposed above a substrate and including a metal oxide layer; a first electrode on the gas-sensitive body layer; and a second electrode on the gas-sensitive body layer, being apart from the first electrode by a gap. The gas-sensitive body layer has a resistance change characteristic that reversibly transitions to a high-resistance state and a low-resistance state on basis of a voltage applied across the first electrode and the second electrode. At least a part of the gas-sensitive body layer is exposed to the gap. The gas-sensitive body layer has a resistance that decreases when gas containing a hydrogen atom is in contact with the second electrode.
