Hybrid microcavity humidity sensor
Applied Physics Letters, 2013This work presents an optical humidity sensing technique based on the combination of a whispering gallery mode microtoroidal cavity sensor and a nm-scale thick humidity-responsive polymer coating deposited via the initiated chemical vapor deposition process.

Integrated multifunctional humidity sensor
Sensors and Actuators A: Physical, 1997Abstract The construction and characteristics of sorption polymeric relative humidity sensors, sorption SiOx microhumidity sensors and condensation- type (dew-point) sensors are compared. The characteristics of the sensors are examined in a dew-point range from − 80 to + 20 °C.

Fiber-optic sensor for humidity
Optics Letters, 1989A novel fiber-optic humidity sensor is described. It is based on reversible sorption of water from the ambient atmosphere in a porous thin-film interferometer that sits on the tip of a fiber. The sorbed water changes the refractive index of the thin films and thus the reflectivity of the interferometer; the resulting modulation of the reflected ...

Investigation of conductometric humidity sensors
Talanta, 1997Sensors for determining humidity in air have been described and investigated. Sensing film of the devices was prepared from polyvinylalcohol and graphitized carbon black disperse phase. The composition, thermal treatment and design of sensing films were investigated and optimized.
