Researchers from the Technical University of Munich developed this carbon nanotube gas sensor incorporates several unique features that are currently other technologies can not achieve. They can quickly detect and keep track of the ammonia, carbon dioxide and nitrogen oxides in the mixed gas content in a very subtle. In addition, they can also work in the room, and consume very little energy. In addition, researchers at the Technical University of Munich thesis in the introduction, this sensor can also be incorporated into the flexible packaging material, so that people on food packaging bags before with bendable, reusable gas sensors vision become a reality, This sensor may provide a more meaningful than the shelf life of food freshness indicators.This smart packaging safe non-toxic non-toxic, it can be used to improve food safety and dramatically reduce food waste.
Technical University of Munich researchers nanoelectronics Araya Abdullah and his colleagues have demonstrated that high-performance gas sensors can be the same as the ink is injected into the soft plastic substrate. Thus, the researchers of this carbon nanotube sensor opens the door to large-scale commercial applications. "When you know how to do when things become very simple." King Abdullah said.
This carbon material is a cylindrical basic molecule, which is determined by a plurality of carbon atoms constituting the honeycomb-type reel format molecules. The carbon nanotube is only a nanometer in diameter, but there are several million nanometers length hollow hoses.As a raw material gas sensors, such nanotubes relative to the polymer organic electronic components and solid metal oxide semiconductor material such as previously used, to achieve the weaknesses in performance, and the current lack of a reliable, renewable inexpensive method for application of this technology.
The researchers found through experiments, spray deposition can completely meet the requirements of the application of this technology. Aqueous solution of carbon nanotubes looks like a bottle of black ink, so we can also be similarly treated carbon nanotubes using spray deposition nozzles controlled by a computer solution is sprayed into the soft plastic substrate.
"For us, the most important thing is to develop an easily measurable technology platform for organic nanometer semiconductor mass production," Abdullah said, "Specifically, the spray deposition processing technology that our The current core. "(Source: machine via network)
