The low-cost graphite based pattern on cellulose paper was investigated in the present work. used fabricated by using normal inkjet printer substrate that acted as working well sensing material for humidity measurements. quantitative electrical characterizations were measured different saturated salt-solutions producing relative (RH) of 15%–92% at room conditions 27 °C and 40%RH. developed sens...

Temperature and humidity are essential parameters in monitoring the health of patients critical care. An optical fibre sensor has been developed for simultaneous measurement relative (RH) temperature at a single tip based on reflected intensity. Combining these measurements enables absolute values to be obtained. The is first modified with coating poly(allylamine hydrochloride) (PAH) / silica n...

The larger surface-to-volume ratio of the hierarchical nanostructure means it has attracted considerable interest as a prototype gas sensor. Both TiO2 and SnS2 can be used sensitive materials for humidity sensing with excellent performance. However, TiO2-SnS2 nanocomposites are rarely in detection. Therefore, this work, new sensor was prepared by simple one-step synthesis process based on nano-...

Abstract This work describes the rational design of thin films based on PVP-modified carbon dots for potential resistive humidity sensing application, prepared via spin coating ITO substrates. The modified were manufactured from graphite waste and with PVP to test synergetic effect two materials. surface hydrophilicity, morphology, properties studied. AFM has been performed investigate films’ t...
