ABSTRACT
Polymers in sensors form a remarkable innovation that provides a high level of sensitivity at an extremely low fabrication cost with ease of manufacturability. Most fabricated polymers are environmentally friendly as well, and, hence, their integration into the sensor domain has been widening the application regime of sensors. Various polymers in pure or doped form (with some nanoparticles/other polymers) are highly capable of providing the desired properties, and, hence, depending upon particular applications, specific polymers are utilized. To explore more about the utility of this field, this chapter extensively discusses the classification of polymers depending on their application/characteristic properties and then elaborates on the common usage applications of polymeric impedance sensors. The developing role of polymer-based sensors, such as temperature sensors, pH sensors, gas sensors, ion-selective sensors, stress sensors, and bio-inspired sensors has been initially reviewed in this chapter. Detailed applications of polymeric impedance sensors in wearable or implantable sensors, biosensors, and environmental monitoring are further discussed.
