| Outline of Final Research Achievements |
The purpose of this study was to develop a wearable wireless self-powered urinary-incontinence sensor system with a urine-activated battery as one of the method for effective utilization of energy harvesting. In this research, a self-powered wireless urinary-incontinence sensor system composed of a disposable diaper-shaped urine-activated battery that is safe for humans and an intermittent-power-supply circuit with low-voltage start-up converter was developed that determines the time for a diaper change. The urine-activated battery and the intermittent-power-supply circuit make it possible to detect the number of incidents and the amount of urine in a diaper from the spacing between the sensing signals.
