The aim of the study - the development of textile screen printed sensor for enuresis alarm system, using different concentrations of graphite in paste and various width of traces (3, 5, 7 mm). The most optimal parameters of concentration (22%) and width (7 mm) of traces, which were printed on sateen weave cotton fabric, are found by measuring the resistivity and the change of voltage in time during dropping the salty dilution. The more graphite concentration and width, the less resistivity is observed.
