Development of Self-Destructive Urine Detection Film Using Water-soluble Resin

The increasingly aging population in Japan, has given rise to a shortage of caregiver availability. By the year 2025, it is projected that there will be a need for 380,000 caregivers. One of Caregivers' compulsory tasks consists in checking diapers every 2 hours both during the day and at night. It becomes even more burdensome when they must also do this around or after midnight, depriving them of quality sleep. The use of excretion detector devices may provide a solution to this problem. However, there are sanitary limitations to the recovery and reuse of such devices. Additionally, there is obvious discomfort that comes with attaching a large device to a diaper. To address this challenge, the disposability, and ultra-thinness of the device presented in this study are paramount. We developed and evaluated disposable film-based urine detector devices for caregivers use.
