  The interest in poly(ionic liquids) for sensing applications are derived from
their strong interactions to a variety of analytes. By combining the desirable
mechanical properties of polymers with the physical and chemical properties of
ILs, new materials can be created. The tunable nature of both ionic liquids and
polymers allows for incredible diversity, which is exemplified in their broad
applicability. In this article we examine the new field of poly(ionic liquid)
sensors by providing a detailed look at the current state-of-the-art sensing
devices for solvents, gasses, biomolecules, pH, and anions.
