1. A leak detection system comprising:
a sensor having a first state comprising a first condition when dry and a second condition when wet for measuring fluid leakage, and a second state adapted to monitor the operability of the sensor;
a communication device operatively connected to the sensor; and
an attachment element adapted to attach the leak detection system to a fluid component, wherein the sensor comprises at least two detection elements mounted on a substrate, wherein each of the detection elements comprises an electrical circuit comprising a plurality of serpentine parallel wires, wherein monitoring the operability of the sensor comprises monitoring the ability of the sensor to detect the fluid leakage of the first state thereof, wherein the electrical circuit allows a measured property of the first condition across a pair of the plurality of serpentine parallel wires and a measured property of the second condition, wherein the measured property of the second condition is at least one of resistance, impedance, capacitance, current, or voltage, wherein the substrate is formed of a wicking and expanding material; wherein at least one of the detection elements is disposed of vertical overlapping wires within layers of the substrate.
