Metal Oxide Nanostructures As Gas Sensing Devices

Eranna (sensor and nanotechnology, Central Electronics Engineering Research Institute, Pilani, India) develops an integrated miniature gas sensor that is compatible with modern semiconductor fabrication facilities so that a small, compact, low-power device can be created that will be useful in analyzing air ambiance with handheld systems. There are presently no specific sensing elements for specific gaseous species, he says, but studies show metal oxide to be sensitive to a group of species, and nanostructures can add their sensitivity to their capabilities. Among his topics are miniaturized solid-state gas sensors, gas-sensing materials and devices, advantages of nanomaterials, nanostructured metal oxides and gas-sensing devices, and active devices based on nanostructures.
