ABSTRACT
James et al. First described in 1971 the quantification of urine loss to determine response before and after treatment [1]. This was achieved using a pair of elongated electrodes embedded within the absorbent layer of a diaper, which contained dry electrolytes. Following urine loss, the moisture between electrodes resulted in a change in electrical conductivity that could be detected and recorded. It was marketed under the name of urilos (N. H. Eastwood & Son, Ltd, London, England) [2]. However, the equipment was rather cumbersome and never caught on.
