TiO2 based surface acoustic wave gas sensor with modified electrode dimensions for enhanced H2 sensing application

The design and optimization of nanostructure-based surface acoustic wave (SAW) gas sensor is analyzed based on TiO2 sensing layer and modified electrode dimensions. The sensitivity of the gas sensor depends upon the type of sensing layer used and active surface area obtained by varying the aspect ratio. The performance of the sensor is observed from 0.1ppm to 100ppm concentration of ...

Gas-detecting properties of surface acoustic wave ammonia sensors

The detecting properties of l-glutamic acid hydrochloride that is deposited on 128◦ YX-LiNbO3 surface acoustic wave (SAW) delay lines are studied in this work. SAW gas sensors that were based on l-glutamic acid hydrochloride had good sensitivity, selectivity, reversibility, and repeatability to ammonia gas. A detection limit of 0.56 ppm for gaseous ammonia was observed when using l-glutamic aci...

Enhanced Sensitivity of Wireless Chemical Sensor Based on Love Wave Mode

A 440MHz wireless and passive Love-wave-based chemical sensor was developed for CO2 detection. The developed device was composed of a reflective delay line patterned on 41 YX LiNbO3 piezoelectric substrate, a poly(methyl methacrylate) (PMMA) waveguide layer, and Teflon AF 2400 sensitive film. A theoretical model is presented to describe wave propagation in Love wave devices with large piezoelec...

Enhanced Sensitive Love Wave Surface Acoustic Wave Sensor Designed for Immunoassay Formats

We report a Love wave surface acoustic wave (LW-SAW) immunosensor designed for the detection of high molecular weight targets in liquid samples, amenable also for low molecular targets in surface competition assays. We implemented a label-free interaction protocol similar to other surface plasmon resonance bioassays having the advantage of requiring reduced time analysis. The fabricated LW-SAW ...

A theoretical study on the adsorption behaviors of Ammonia molecule on N-doped TiO2 anatase nanoparticles: Applications to gas sensor devices

We have performed density functional theory investigations on the adsorption properties of ammonia molecule on the undoped and N-doped TiO2 anatase nanoparticles. We have geometrically optimized the constructed undoped and N-doped nanoparticles in order to fully understand the adsorption behaviors of ammonia molecule. For TiO2 anatase nanoparticles, the binding site is preferentially located on...
