Title:
EXCREMENT SENSOR AND PREPARATION METHOD
Document Type and Number:
Japanese Patent JP2020169975
Kind Code:
A
Abstract:
To provide a simple, effective, and low cost excrement sensor.SOLUTION: An excrement sensor comprises a thin-film capacitive sensor. The sensor comprises a sensing bar. The sensing bar comprises an upper waterproof film, a lower waterproof film, a first detection electrode 21, a second detection electrode 22, and a first notch. One surface of the upper waterproof film and the lower waterproof film is bonded with each other to form an insulating interlayer. A main body part of the first detection electrode is located in the interlayer. The first notch penetrates the upper waterproof film, the lower waterproof film, and the first detection electrode located in the interlayer. As a result, the first detection electrode in the interlayer is exposed outwards through the first notch to form a first sensing line 21c, the first sensing line is in contact with an excrement 16 to be detected to generate a first double-electric-layer capacitor C1, and capacity of the first double-electric-layer capacitor is in direct proportion to a coverage range of the excrement to be detected on the first sensing line.SELECTED DRAWING: Figure 6a
