Abstract
Disclosed herein are systems and devices which are capable of detecting moisture and remotely indicating when the presence of moisture is detected. The systems utilize multilayer sensors that consist of two conductive layers surrounding an insulating, spacer layer. Nonwoven materials with conductive additives have shown particular advantages for use in constructing the conductive sensor layers. The multilayer sensor can be electrically coupled to a transmitter that is itself in electrical communication with one or more receiver devices. The transmitter and receiver devices are configured to provide indicators when moisture is detected through audible signals, vibration, visible signals or through notifications displayed on a software application. The sensor and/or the transmitter may be attached along a perimeter of the layers. The layered sensor may be affixed to an inside or outside of a package for location tracking, or may be attached to or incorporated in a diaper, as non-limiting examples.
