Polymer-Based Capacitance Gas Sensors

It should be noted that the most widely used materials in capacitance-type gas sensors are polymers (Chatzandroulis et al. 2011). They are particularly suitable for sensing organic vapors and other types of analytes (see Table 16.1) because they exhibit rapid reversible vapor sorption and are easy to apply
