Using Pt Dopant and Sol Gel Technology for Sensitivity Enhancement of TiO2/SnO2Humidity Sensors.

The sensitivity of the humidity sensor based on hybrid thin films of nanostructure TiO2/SnO2with Pt dopant was successfully increased. The humidity-sensitive materials, TiO2/SnO3, were prepared by sol gel technology. The microstructure of the sensing film after calcination was investigated by the Field Emission gun Scanning Electron Microscopy (FESEM) and revealed that the metal oxide hybrid had about 10 nm grain size.

Phase Detection of the Two-port FPW Sensor for Biosensing.

In this study, we provided a comprehensive methodology for designing and integrating miniature system in the biosensor application. In general, the network analyzer is commonly used for acoustic wave sensor measurement. However, it is remarkably inconvenient for portable use.
