Description
Technical Field
The invention relates to the field of detection equipment for urination and defecation of infants, infants and persons suffering from urination and defecation incontinence, in particular to a capacitive sensor for enuresis detection.
Background
At present, although the baby diapers sold in the market can absorb urine, the baby diapers cannot remind people of replacing the baby diapers in time. If the diaper can not be replaced in time after the baby loses urine, the skin of the baby is red and swollen or allergic due to the fact that excrement contacts the buttocks for a long time, and the skin of the baby is damaged. Meanwhile, the infant also has the condition of enuresis in a bed when sleeping at night, and the skin of the infant is also unfavorable if the infant cannot be found and treated in time. Furthermore, some individuals who are disabled in society may also experience similar problems in some cases. In view of the above social problems, it is desirable to design a flexible detection sensor that is simple, convenient, low-cost, and reusable for the above situations, and that can detect the above situations and deal with them in time to benefit the health of the above related people.
Disclosure of Invention
