A high-sensitive wireless and passive surface acoustic wave (SAW) humidity sensor operating at 433 MHz was designed and developed. SiO2 thin film with large specific surface was employed as the ...

They’re nearly invisible to the human eye, but smart dust sensors are now being embedded in bridges, factories, and even ...

A capacitive humidity sensor based on porous structure is designed using sol gel method and modeled by calculating different parameters. The influence of relative humidity on the dielectric constant ...
