Abstract
Methods of reducing sensor corrosion include providing a monitor adapted to electrically connect with a wetness sensor integrated with an absorbent article. The wetness sensor has a first conductor and a second conductor and the monitor includes programming instructions that, when the monitor is attached and activated, repetitively execute a sequence of steps that includes applying voltage to the first conductor; measuring the potential across the conductors; and discontinuing the voltage to the first conductor. The instructions may also repetitively execute a sequence of steps that includes alternatively applying voltage to the first and second conductors and/or grounding the first conductor and/or second conductors after discontinuing voltage.
