Care facilities are currently experiencing a serious shortage of manpower, and late-night patrols have become a major burden for caregivers. To reduce this burden, we have developed a water-sensitive urination detection device using UHF RFID without a battery and a sensor IC. In this study, we developed a method to identify and detect the amount of urination in a step-by-step manner when a urine pad is attached to a diaper in order to satisfy the demand for notification in the range of 600 ml to 1000 ml, which is the amount of urine that can be absorbed.We conducted a test to verify the accuracy of the developed method. The results showed that although the F value of the detection rate was low (68.4%), the urination detection rate was 80.0% by adjusting the number of times of notification in consideration of the detection rate.
