Abstract
Polymers play a major role in sensor research nowadays. Specifically, when
the electrical modality of sensing is concentrated then conducting polymers is found to
be highly useful. They have been explored for the development of sensors to cope with
advanced modern-day requirements. There is a huge demand for sensors in detecting
and assessing environmental dynamics, harmful working conditions, food poisoning,
and water contaminations, and diagnostic purposes. The recent pandemic, the COVID-19 outburst all over the world, ascertained the urgency of research in the direction of
designing and developing biosensors enabling distinction among the diseases and
enabling medical professionals to take faster clinical decisions. The conventional
approaches in environment pollutant detection techniques have no universally accepted
code of conduct. Moreover, there are various experimental drawbacks of poor
calibration, tedious sample preparation, blank determination, and lengthy time-consuming procedure. The composites involving conducting polymers and CNTs bring
in unique multifunctional features. The motive of the present work is to review various
latest developments in conducting polymer composite-based sensors.
