Microfabricated Formaldehyde Gas Sensors
Formaldehyde is a volatile organic compound that is widely used in textiles, paper, wood composites, and household materials. Formaldehyde will continuously outgas from manufactured wood products such as furniture, with adverse health effects resulting from prolonged low-level exposure. New, microfabricated sensors for formaldehyde have been developed to meet the need for portable, low-power ga...
متن کاملBlack phosphorus gas sensors.
The utilization of black phosphorus and its monolayer (phosphorene) and few-layers in field-effect transistors has attracted a lot of attention to this elemental two-dimensional material. Various studies on optimization of black phosphorus field-effect transistors, PN junctions, photodetectors, and other applications have been demonstrated. Although chemical sensing based on black phosphorus de...
متن کاملFormaldehyde Gas Sensors: A Review
Many methods based on spectrophotometric, fluorometric, piezoresistive, amperometric or conductive measurements have been proposed for detecting the concentration of formaldehyde in air. However, conventional formaldehyde measurement systems are bulky and expensive and require the services of highly-trained operators. Accordingly, the emergence of sophisticated technologies in recent years has ...
متن کاملAcoustic Wave Hydrogen Gas Sensors
Amorphous titanium dioxide (TiO2) and gold (Au) doped TiO2-based surface acoustic wave (SAW) sensors have been investigated as hydrogen gas detectors. The nanocrystal-doped TiO2 films were synthesized through a sol-gel route, mixing a Ti-butoxide-based solution with diluted colloidal gold nanoparticles. The films were deposited via spin coating onto 64◦ YX LiNbO3 SAW transducers in a helium atm...
متن کاملMetal Oxide Nanowire Gas Sensors
Monocrystalline metal oxide nanowires have emerged as new building blocks for a wide range of devices and applications owing to their unique properties directly derived from their size, crystalline structure and well-defi ned geometry. In particular, these nanomaterials have been successfully integrated in proof-of-concept gas sensors with high sensitivity and stable characteristics, giving ris...
