Multi-objective optimization of the parameters of TiO2-based ceramic humidity sensors

Preparation, Characterization, and Evaluation of Humidity-Dependent Electrical Properties of Undoped and Niobium Oxide-Doped TiO2 : WO3 Mixed Powders

“…ese processes are intrinsically dependent on microstructure and prevailing transport mechanisms of resulting materials. e doping process induced by metal oxides introduces atomic defects which a ect the overall conduction mechanisms of blends, characterizing the relative concentration of a dopant as a tuning parameter in the optimization of electrical response in terms of RH variation [4][5][6][7].…”

Novel humidity sensitive materials derived from naphthalene-based poly (arylene ether ketone) containing sulfobutyl pendant groups

“…[2,3]. Many materials with potential use in humidity sensors have been studied, including ceramics [4][5][6], semiconducting materials [7,8], polymers [9][10][11] and composites [12][13][14][15]. Polymeric humidity sensors have been widely studied for more than 30 years because of many advantages, such as high sensitivity in a wide range of relative humidity (RH), multiformity, flexibility and easy processing [14].…”

Superior Linear Response of K2Ti2O5 in Low and Medium Humidity Ranges

“…To date, most materials have exhibited humidity sensing performance at high humidity levels but are insensitive at low humidity levels. − This becomes a formidable problem that strongly limits the wide practical application of humidity sensors. Therefore, much work is urgently warranted on searching new humidity sensing materials suitable for low humidity level applications. − …”
