Chemical sensors whose active element exhibits both a visual change in color and a measurable change in electrical resistance when exposed to an analyte to which it selectively reacts are provided. These sensor have several unique features including vastly improved stability measured in years, irreversible visual changes and surprisingly reversible electrical changes. The combined unique features enable a new generation of ultra low power alerting, alarming and readout devices for hydrazines and other strongly reducing chemicals.
