Title:
DROPLET SENSOR, DEW CONDENSATION DETECTION DEVICE, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2023/276982
Kind Code:
A1
Abstract:
The present invention provides: a droplet sensor which has stable detection characteristics, little production variation among elements even when mass-produced, and high detection accuracy, and can obtain a high electric output; a dew condensation detection device; and a method for producing the droplet sensor and the dew condensation detection device. This droplet sensor is provided with an insulating substrate, a first electrode having a first thin wire and a first current collector, and a second electrode having a second thin wire and a second current collector, wherein: the first electrode and the second electrode are arranged on the insulating substrate; the first thin wire and the second thin wire are alternately juxtaposed on the insulating substrate; and a galvanic current, which flows between the first thin wire and the second thin wire via a conductive droplet, is detected. The first thin wire is composed of a first metal-containing material layer having a lower electric resistivity than platinum, the second thin wire is composed of a composite film of the first metal-containing material layer and a platinum-containing material including platinum or a platinum alloy, and at least a part of the surface of the platinum-containing material layer is exposed to the outside.
