  • Wetness indicator for alerting a wearer to urination
    Patent number: 7767875
    Abstract: A toilet training wetness indicator for alerting a wearer to urination and a garment incorporating such an element. The toilet training wetness indicator, which may be an insertable wetness indicator or integrated directly into a garment, such as training pants, comprises a liquid permeable enclosure having a liquid absorbent body enclosed therein. The liquid absorbent body absorbs liquid within the pants and applies hydraulic pressure to the enclosure upon absorption of a preselected amount of liquid. The enclosure limits expansion of the absorbent body so that the wetness indicator stiffens as liquid is absorbed. The wetness indicator has a first stiffness and is relatively pliable when dry and a second stiffness greater than the first stiffness upon absorption of the preselected amount of liquid.
