Absorption article and related method thereof

Abstract

The invention provides an electronic humidity-sensing absorption article and a related method thereof. The electronic humidity-sensing absorption article comprises a flexible waterproof membrane, at least two flexible electrodes, a pervious knitted layer and an absorbing layer, wherein the flexible electrodes are mutually separated and insulated and are arranged on one side of the flexible waterproof membrane; and the absorbing layer is arranged on the other side of the flexible waterproof membrane, positioned between the flexible waterproof membrane and the pervious knitted layer, and used for absorbing liquid entering from the pervious knitted layer. The flexible waterproof membrane, the flexible electrodes and the liquid contained in the absorbing layer form a non-polar variable electrolytic capacitor, wherein the flexible electrodes serve as the electrodes of the electrolytic capacitor, the flexible waterproof membrane serves as a dielectric medium of the variable electrolytic capacitor, the liquid serves as the electrolyte of the electrolytic capacitor, and by detecting the capacitance value and change thereof of the variable electrolytic capacitor, the humidity state of the electronic humidity-sensing absorption article can be learned.

Description

technical field [0001] The invention relates to an absorbent article, in particular to a disposable liquid absorbent article which can provide dynamic absorption process information and its analysis and production method. Background technique [0002] Disposable absorbent products include absorbent products such as paper diapers, paper diapers, paper changing pads, and sanitary napkins. All of the disposable absorbent products need to be replaced in a timely manner. If the replacement is too frequent, it will not only cause trouble but also waste; but if Changing it too late can cause liquid leakage problems because absorbent articles have a limited absorbency. How to dynamically detect and display the user's excretion situation, including the frequency of excretion, excretion volume, and whether the absorption capacity of the absorbent article is close to saturation, has considerable reference value for the rational use of the absorbent article. [0003] However, the infor...
