The front elastic waistband 3 and the rear elastic waistband 4 at the front and rear ends of the diaper body 1 are bonded and fixed together, and the wearing work of the smart diaper specially designed for bedridden elderly people is completed. When the bedridden elderly people are in bed, the temperature sensor 12 is used to monitor the body temperature of the bedridden elderly people in real time and send it to the external controller 2 for display. At the same time, the body position sensor 13 is used to monitor the body characteristics of the bedridden elderly people in real time and send the corresponding data to the external controller 2 for display. When the bedridden elderly people urinate, the liquid absorption area 5 absorbs urine. Using the conductivity of urine, when the urine contacts the conductive ink strip 6, a closed circuit is formed, resulting in a change in resistance. At this time, the resistance sensor 7 is used to monitor the resistance change of the conductive ink strip 6 in real time to determine whether urination occurs, and the judgment result is sent to the external controller 2 for display, so as to prompt the nursing staff to take care of the bedridden elderly people in time.
