A combination of pad-type and pants-type disposable diapers are used in nursing homes for the elderly in Japan. In this study, a torso was fitted with a pad-type diaper and a pants-type diaper. Electrodes were attached to the outside of the pants-type diaper to evaluate the urine absorption volume of the pad-type diaper. The capacitance of the electrodes increased linearly with the increase in the water absorption volume of the pad-type diaper. A subject wore the diapers and the electrodes and discharged his urine into the pad-type diaper. The capacitance of the electrodes increased, and the urine absorption volume was estimated by the increase in the capacitance of the electrodes.
