Abstract
An absorbent article for absorbing liquid discharge of a wearer includes conductive loops each in an open loop shape having terminal ends for electrically communicating with opposing poles of an electric potential generator such that current flows around the full conductive loop between the terminal ends when a space defined within the open loop shape is dry and such that liquid discharge in the space defined within the open loop shape is able to cause a short circuit in the conductive loop so that the current flows around a reduced impedance path. The impedance change is measurable to determine a location relative to the terminal ends where the liquid discharge has caused the short circuit. The conductive loops are oriented such that the direction in which the current travels up an outward leg of the respective conductive loop is in substantially the opposite direction for a first conductive loop as for a second conductive loop.
