乳幼児を対象とした尿流率計測のためのオムツ吸水層内尿拡散取得

In this paper, we propose a novel urine rate measuring system for infants and children. The uroflowmetry(UFM) is known as a diagnostic procedure for urinary tract disease. However there is no diagnostic equipment for infants and children. In consideration of physical constraints and load on infants, We embed a two-dimensional electrode array sensor with lightweight and flexible in the diaper water-absorbing layer. By utilizing the fact that the impedance between electrodes varies on the amount of urine contacting them, we estimate flow rate of urine diffusing in the water-absorption layer. In this paper, we describe the configuration of the flow rate estimation system based on the impedance distribution and the basic experiment results.
