SAW Sensors for Chemical Vapors and Gases
Surface acoustic wave (SAW) technology provides a sensitive platform for sensing chemicals in gaseous and fluidic states with the inherent advantages of passive and wireless operation. In this review, we provide a general overview on the fundamental aspects and some major advances of Rayleigh wave-based SAW sensors in sensing chemicals in a gaseous phase. In particular, we review the progress i...
متن کاملMetal-organic frameworks as sensors: a ZIF-8 based Fabry-Pérot device as a selective sensor for chemical vapors and gases.
A ZIF-8 thin film-based Fabry-Pérot device has been fabricated as a selective sensor for chemical vapors and gases. The preparation of the ZIF-8 thin film and a series of ZIF-8 thin films of various thicknesses grown on silicon substrates are presented.
متن کاملLocal/global Saw Sensors for Turbulence
A new surface acoustic wave (SAW) sensor is developed through theoretical and experimental investigation to detect the surface forces (wall pressure and wall friction) and the direction of the turbulent flow as a function of position and time on the structure. The sensor is composed of a pair of SAWs having an identical center frequency with surface waves experencing shear stresses in opposite ...
متن کاملFabrication of High Frequency Surface Acoustic Wave (saw) Devices for Real Time Detection of Highly Toxic Chemical Vapors
In this paper, a low cost fabrication of sub micron features size SAW device with conventional lithography and their application for toxic chemical vapor detection has been presented. The SAW devices with different interdigital transducer (IDT) electrodes line widths were designed and fabricated. The fabricated SAW devices features had an accuracy of ± 0.1 μm. Frequency response of the SAW devi...
متن کاملThe biological and toxicological activity of gases and vapors.
A large amount of data on the biological and toxicological activity of gases and vapors has been collected from the literature. Processes include sensory irritation thresholds, the Alarie mouse test, inhalation anesthesia, etc. It is shown that a single equation using only five descriptors (properties of the gases and vapors) plus a set of indicator variables for the given processes can correla...
