1. A corrosion sensor for deployment in a structural cable of multiple wires, comprising:

  • a casing; and

    a first counter-electrode configured to exchange electrons with ions of an electrolyte that corrodes the multiple wires of the structural cable,whereinthe casing is shaped to mimic interstitial spaces between the multiple wires of the structural cable along a length equal to a distance more than one wire diameter of a wire of the multiple wires, and,the first counter-electrode is embedded in the casing, is exposed in a first window of the casing, and is recessed to avoid contact with any wire of the structural cable when the sensor is deployed among the multiple wires of the structural cable.
