Title:
ABSORPTION STATE MONITORING SENSOR FOR DISPOSABLE ABSORPTION ARTICLE, RELATED PRODUCT AND METHOD
Document Type and Number:
WIPO Patent Application WO/2021/088761
Kind Code:
A1
Abstract:
An absorption state monitoring sensor for use in a disposable absorption article, comprising a first detection circuit (20a), waterproof protection mechanisms (231, 271), and an infiltration diffusion control mechanism. The first detection circuit (20a) comprises a first detection electrode (21) and a second detection electrode (22). The first detection electrode (21) and the second detection electrode (22) comprises a protected electrode part and an unprotected electrode part. When excreta containing electrolyte liquid exist in the absorption article, an electrical double-layer capacitor may be generated between the first detection electrode (21) and the second detection electrode (22). The capacitance value of the capacitor is in positive correlation with the specific surface area of the unprotected electrode part infiltrated by the electrolyte liquid, and the specific surface area is gradually increased under the infiltration diffusion control mechanism. Provided are a disposable intelligent absorption article capable of providing absorption state information, a method for manufacturing an absorption state monitoring sensor, a method for manufacturing a disposable intelligent absorption article, and a method for distinguishing urine and feces. The sensor is low in cost, easy in production and good in commonality, etc.
