Abstract
An absorbent article facilitating sensing the presence of a body exudate in the absorbent article includes an absorbent member; a sensor coil disposed on or in the article; and an electrical double-layer capacitor disposed on or in the article and in electrical communication with the sensor coil, wherein the capacitor is in fluid communication with the absorbent member. An absorbent article system also includes a detector circuit including an exciter coil configured for electromagnetic communication with the sensor coil, and sensor electronics configured to indicate the presence of a body exudate based on changes in the electromagnetic communication between the exciter coil and the sensor coil.
