Polymer-based sensors: A review

Polymers are indispensable component of modern sensor devices. Gauges play an important role in medicine, control of chemical reactions and identification of gases or may even be used as electric noses or tongues. These and many other types of sensors are described in the given article and some real-time applications examples are given among varied types of polymer-based sensors. However, studies on polymer sensors are still ongoing. New solutions are being sought and the mechanisms of the specific reactions occurring in polymer sensors are not fully understood. Their in-depth analysis still requires tremendous work. The attention of this article is drawn to the trends and challenges present in this field of study.
