Absorbent article and related method

Abstract

The present invention provides an electronic moisture-sensitive absorbent article and related methods thereof. The electronic moisture-sensitive absorbent article comprises: a flexible waterproof film; at least two flexible electrodes arranged on one side of the flexible waterproof film; and a water-permeable braid layer; The absorbent layer arranged on the other side of the flexible waterproof film and between the flexible waterproof film and the water-permeable fabric layer is used to absorb the liquid entering from the water-permeable fabric layer; the flexible waterproof film, flexible electrodes and the liquid contained in the absorbent layer A non-polar variable electrolytic capacitor is formed, wherein the flexible electrode is used as the electrode of the electrolytic capacitor, the flexible waterproof film is used as the dielectric of the variable electrolytic capacitor, and the liquid is used as the electrolyte of the variable electrolytic capacitor. The change is detected, and the wet state of the electronic moisture-sensitive absorbent article can be known.

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...

Problems solved by technology

[0003] However, the information provided by traditional urine wetness detection technology is limited. One of the most common technologies is to short-circuit the electrodes through urine to generate a urine wetness reminder signal. In principle, this urine wetness detection method can only detect whether the urine is wet. The degree of urine wetness cannot be detected, nor can it provide dynamic information about the wet process and whether the absorption capacity of absorbent articles is close to saturation. This requires a new technical solution to solve the problem.
