1. A moisture detection system comprising:
a transmitter; and
a layered sensor connected to the transmitter, the layered sensor comprising a first conductive layer, a second conductive layer, and a separator layer, wherein
(a) the first conductive layer, the second conductive layer, and the separator layer are approximately planar sheets of material,
(b) the separator layer is (i) disposed above the first conductive layer and frictionally contacts the first conduct layer, and (ii) disposed below the second conductive layer and frictionally engages the second conductive layer,
(c) the conductive layers form a closed circuit in a dry state,
(d) the conductive layers form an open circuit when moisture is present in the separator layer between the first conductive layer and the second conductive layer, and the moisture contacts both the first conductive layer and the second conductive layer, and
(e) the transmitter detects an absence of a signal from the formerly closed circuit and generates a detection signal.
