Semiconducting metal oxides (SMOXs) are used widely for gas sensors. However, the effect of ambient humidity on baseline and sensitivity chemiresistors is still a largely unsolved problem, reducing sensor accuracy causing complications calibrations. Presented here general strategy to overcome water-sensitivity issues by coating SMOXs with hydrophobic polymer separated metal–organic framework (M...

The application specific paper describes a design approach for digital humidity sensors, data acquisition systems, data loggers and multisensors systems. Practical realizations are based on the Universal Frequency-to-Digital Converter (UFDC-1). Such design approach lets significantly simplify the design process, reduce time-to-market and production price and produce multisensors systems with hi...

The present study highlights the interdependence of ambient humidity levels on the electrical parameters of organic-inorganic hybrid composite based humidity sensor at varied AC frequencies of input signal. Starting from the bottom, the layer stack of the fabricated humidity sensor was 200-nm silver (Ag) thin film and 4 μm spun-coated PEPC+NiPC+Cu2O active layer. Silver thin films were deposite...

We have examined the effects of oxygen content and thickness in sputtered InSnO (ITO) electrodes, especially for the application of imperceptible amorphous-InGaZnO (a-IGZO) thin-film transistors (TFTs) in humidity sensors. The imperceptible a-IGZO TFT with 50-nm ITO electrodes deposited at Ar:O₂ = 29:0.3 exhibited good electrical performances with Vth of -0.23 V, SS of 0.34 V/dec, µFE of 7.86 c...
