The present chapter describes the synthesis and applications of different
classes of nanocomposites in humidity sensing applications, along with their innovative
surface and responsive properties. The uses of nanocomposite-based humidity sensors
in different fields like environmental monitoring, packaging, and the medical field have
been described with suitable examples and illustrations. Furthermore, the humidity
sensing mechanism of nanocomposite based humidity sensors are explained with
sensing parameters and with future requirements.
Keywords: Humidity sensors, Hybrid materials, Sensing mechanism, and applications.
